WORKING PRINCIPLE

Dropwise Condensation

In dropwise condensation, vapour condenses on the surface in the

form of drops, and consequently a large part of cooling surface is always bare to

vapour for undergoing consideration. ( Fig.) The rate of heat transfer is many

times larger than what is achieved in firm condensation. Dropwise condensation

occurs on a nonwettable cooling surface where the liquid condensate drops do not

spread.

Let us explain briefly what is wettable or a nonwettable surface. The

surface of liquid always tends towards a minimum. A freely suspended drop of

liquid always takes the shape of sphere which is of the geometrical shape having

the minimum surface area for the same volume. This is due to the effect of

surface tension. Surface tension always exists whenever there is a discontinuity in

the material medium. Mercury in contact with air has a certain surface tension.

With water, mercury has another surface tension. Let us consider the equilibrium

of a liquid drop on a solid surface ( Fig. ) being the surface tension as shown.

Fig. : Equilibrium of a liquid drop on a solid surface

If 1 cos + 3 = 2, the liquid iron drop remains in equilibrium

and does not spread. The surface is nonwettable ( e.g. mercury in glass )

2 - 3cos 1 = = - cos

2 - 3cos = = where is the angle of contact.

If ( 1 cos + 3 ) > 2, the liquid drop spreads and the surface is wettable

( e.g. water in glass ). When is obtuse, he surface is nonwettable, and if is

acute, the surface is wettable.

Dropwise condensation is much desirable because of its higher heat

transfer rates. However, it hardly occurs on a cooling surface. When the surface

is coated with some promoter like mercaptan, oleic acid and so on, drop

condensation can occur for some time. But the effectiveness of the promoter

gradually decays due to fouling, oxidation or its slow removal by the flow of the

condensate. Condensers are usually designed on the basis that film condensation

would prevail.

Greenhouse Effect

Glass transmits over 90 % of radiation in the visible range and is

almost opaque to infrared wavelengths ( > 3 m ). Thus, glass allows the

solar radiation to enter, but does not allow infrared radiation from the interiorsurfaces to exit. This causes a rise in the interior temperature, with heat thus being

trapped. This heating effect due to the nongray characteristic of glass or clear

plastics is known as the greenhouse effect. (Fig.)

Fig. : Greenhouse which traps energy by allowing the solar radiation to come

in, but not allowing the infrared radiation to go out.

The greenhouse effect is also experienced on a larger scale on earth.

The surface of the earth, which warms up during the day as a result of the

absorption of solar energy, cools down at night by radiating its energy into deep

space as infrared radiation. The gases CO2 and H2O vapour in the atmosphere

4

transmit the bulk of the solar radiation during the day, but absorb infrared

radiation emitted by the surfaces to the earth at night. Thus, the energy trapped on

earth by the atmosphere causes global warming, and drastic changes in whether

conditions.

Absorptivity, Reflectivity And Transmissivity

Matter can emit, absorb, reflect and transmit radiant energy. If Q is

the total radiant energy incident upon the surface of a body, some part of it ( Q A)

will be absorbed, some part ( QR) reflected and some part ( QTr ) transmitted

through the body ( Fig. ). By energy balance,

QA + QR + QTr + = Q

QA + QR + QTr

or, = 1

Q Q Q

+ + = 1

Where is the fraction of incident radiation which is absorbed, called

absorptiviti, is the fraction which is reflected, called reflectivity, and is the fraction

which is transmitted through the body, called transmissivity or transmittance.

A body is said to be opaque if = 0 and + = 1. Most solids

do not transmit any radiation and are opaque. If is reduced, increases. The

reflectivity depends on the character of the surface. Therefore, the absorptivity of

an opaque body can be increased or decreased by appropriate surface treatment.

When the surface is highly polished, the angle of incidence 1 is

equal to the angle of reflection r , and the reflection is said to be specular. When

5

the surface is rough, the incident radiation is distributed in all directions, and the

reflection is said to be diffuse. ( Fig. )

Most gases have high value of and low values of and . Air

at atmospheric pressure and temperature is transparent to thermal radiation for

which = 1 and = = 0. Gases like CO2 and H2O vapour are highly

absorptive at certain ranges of wavelengths.

Power Density

The insolation is the power incident on a unit area of surface. Near

equatorial regions the radiant power density is about 1.4 kW/m2 on a horizontal

surface at noon. This quantity varies with time of day and with latitude in two

time cycles : the day ( 8.64 x 104 sec. ) and the year ( 3.15 x 107 sec. ). At the

higher latitudes, the lower thermal input results in a colder climate. At any time,

solar power is attenuated by the atmosphere and its components molecular gases,

clouds, and dust. The fraction absorbed or reflected by the atmosphere depends on

meteorological, geological ( e.g., volcanoes ), and geometric aspects. The

geometric factors result in variations in the solar power over time and location as

shown in Fig.

An important aspect of solar power is that a large surface area is

required to collect amounts of it which compare to that currently provided by

fossil fuels. Consider each persons continuous need for 1-10 kW the range of

which depends on economic status from Third World inhabitant to industrial man.

The atmosphere absorbs on average 30 % of the solar power ( this fractiondepends strongly on the local climate ), which is available only about 35 % of the

time ( the rest of the time is twilight and night ), and can be collected for present

or later use with an efficiency of say 10 %. These considerations alone dictate

that, on a per capita basis, the surface area requirement of the order of 30-300 m2

( 300-3000 ft2). This area requirement is significantly larger than that required for

food production alone. Setting aside the question of cost for this area, it is

doubtful that is would even be available where it is needed: in or near cities and

towns. If one takes the view that solar energy is to be used for supplying all of the

needs of US inhabitants ( 200-300 million ), then the land area required is about

one entire large western state. The environmental impact is certainly severe. Even

if such power-gathering systems were distributed throughout the land, it would be

8


9/37


difficult to have a place where it would not have at least a visual impact. The

ocean surface has been suggested for such a purpose. If such numbers are applied

to western Europe or some regions of Asia, where the population density is large,

the difficulty of replacing present fossil fuel exploitation with solar power

becomes apparent.

It can also give cooling effect into factory because some of the heat

is absorbed by water and fiber glass sheet rest of the heat is reflected thus it gives

cooling effect to the area coming under the aforesaid instrument.

You know that the precision machinery viz. CNC machine &

computer system are kept in totally packed controlled room as there is a need of

Air-conditioned system to make temperature at about 250C & humidity 50 %.

Thus if we use this instrument as a roof then it will automatically save electricity

in the form of light source. And some electricity use for Air conditioning .

USE OF FIBERGLASS

Fiberglass Production

The production of glass fibers starts with dry mixing of silica sand

and limestone, boric acid and a number of other products such as clay, coal and

fluorspar. These materials are melted in a high-refractory furnace, the

temperature of the melt being dependent on the glass composition, but s generally

about 12600 ( 23000 ). The molten glass then flows directly to the fiber-drawing

furnace in a direct melt flow process or into a marble making machine. These

marbles can be sorted and can eventually be remelted and drawn into fibers.

Continuous glass fibers are produced when molten glass from the

fiber-drawing furnace is gravity fed through numerous tiny openings in a platinum

alloy tank called a bushings. The droplets of molten glass that extrude from each

of the bushings openings are gathered together, mechanically attenuated to the

correct dimensions, passed through a water spray and over a revolving belt that

applies a protective and lubricating coating known as a size or binder. The fibers

are then gathered together in a suitably shaped shoe to form a bundle called a

strand which is wound onto a core at approximately 190 / km / h ( 120 mile / h ).

This package of fibers is then dried or conditioned prior to further processing and

eventually sold as a continuous filament yarn.

1


16/37


Staple fibers are produced by passing a jet of air across the openings

at the base of the bushing, which pulls individual fibers of approximately

20 40 cm ( 8-15 in ) long from the molten glass that is extruding from each

opening. These filaments are collected on a collected on a rotating vacuum drum,

sprayed with size and gathered into a strand. This package of filaments is again

conditioned or dried prior to processing into a specific product for further use.

Each individual fiber is drawn from the bushing opening and must

be controlled so that responducible filaments, strand dimensions and properties are

obtained. This control is achieved by the regulation of the melt viscosity,

temperature and drawing speed. It is possible, therefore, to obtain a large number

of filament diameters by varying the number of openings in the bushing and the

drawing conditions.

As demand has dictated over the years, the fiberglass industry has

established a number of standard filament diameters.

Glass Composition

Glass is generally defined as an amorphous material, being neither

solid or liquid. Chemically glass is made up of elements such as silicon, boron

and phosphorus that are converted into glass when combined with oxygen, sulfur,

tellurium and selenium. The molecular arrangement is conducive to formation

of an intricate three-dimensional network of oxygen tetrahedral with a silicon

atom in the middle, bonded to each oxygen atom. Silicon by itself requires

extremely high temperatures for liquefaction. Therefore, other elements are added

to the mix to reduce temperatures and to produce a viscosity in the molten glass

that will allow easy drawing.

A number of glass compositions are available depending on the

properties desired from the resulting fibers.

Types of Fiberglass

1


19/37


1) A-glass : A high alkali or soda glass is made into fibers for use in

application where good chemical resistance is needed.

2) E-glass : A low alkali glass, based on aluminum borosilicate. This glass

possesses excellent electrical insulation properties and is the premium fiber

used in the majority of textile fiberglass production.

3) C-glass : A material based on soda borosilicate that produces a fiber that

offers excellent chemical resistance.

4) S-2 glass : This glass is made up of magnesium, aluminum silicate and

offers higher physical strength. Fibers produced from this glass have an

approximate forty percent tensile strength improvement over those of E-

glass composition.

5) D-glass : This fiber made from a low dielectric composition has dielectric

loss properties ( dielectric constant of 3.8 at 1 mc s-1 ) superior to that of E-

glass ( 6.0 at 1 mc s-1 ).

6) R-glass : A special glass composition that produces fiber that is alkali

resistant and is used in reinforcing concrete.

7) Low K : An experimental fiber produced to improve dielectric loss

properties in electrical applications ( similar in performance to D-glass ).

20/37


8) Hollow fiber : Special glass whose fibers are tube-like or hollow; the

material has specific applications in reinforced aircraft parts where weight

could be significant.

9) Te glass : A Japanese manufactured S-glass, for higher strength structural

application.

A - Glass fiber for acid resistance.

C - Glass fiber for improved acid resistance.

D - Glass fiber for electronics applications.

E - Glass fiber for electrical insulation.

S - Glass fiber for high strength.

21/37


Fiberglass Properties

1) High tensile strength : Fiberglass has an exception ally high tensile

strength compared with other textile fibers. Its strength to weight

ratio exceeds steel wire in some applications.

2) Heat and fire resistance : Because fiberglass is inorganic it does

not burn or support combustion.

3) Chemical resistance : fiberglass has excellent resistance to most

chemicals and is impervious to fungal, bacterial or insect attack.

4) Moisture resistance : Because fiberglass does not absorb water, it

neither swells, stretches nor disintegrates. Fiberglass does not

readily rot and continues to maintain its mechanical strength in

humid environments.

5) Thermal properties : Due to its low coefficient of thermal linear

expansion and high coefficient of thermal conductivity, fiberglass

exhibits excellent performance in thermal environments.

6) Electrical properties : Fiberglass being nonconductive is an ideal

choice for electrical insulation, where designers can make use of the

high dielectric strength and low dielectric loss properties.

SCARCITY OF CONVENTIONAL ENERGY SOURCES

The need for Alternatives

Based on the preceding survey, it will now be possible to make some

observations and draw some conclusions for the world as a whole.

Fossil Fuels :-

1. The production of oil appears to have touched a maximum

around 1980 and is now slowly declining. On the other hand, the

production of natural gas is still increasing. Present indications are

that most of the reserves of oil and natural gas are likely to be

consumed in another 50 years.

2. As oil and natural gas become scarcer, a greater emphasis will

fall on coal. It is likely that the production of coal will touch a

maximum some where between the years 2030 and 2060 and that 80

percent of the amount available could be consumed by 2250 AD.

3. It should also be noted that in addition to supplying energy,

fossil fuels are used extensively as feedstock material for the

manufacture of organic chemicals. As reserves deplete, the need for

using fossil fuels exclusively for such purposes may become greater.

2


25/37


Water Power :-

There is considerable scope for increasing the capacity of water

power all over the world. Water power is indirectly obtained from solar energy

and has the advantage of being a renewable source of energy.

Nuclear Power :-

The position regarding uranium is serious if we continue to use it as

at present in burner rectors.

It is thus fairly evident that a need exists for developing alternative

energy sources. The immediate need would be to alleviate the problems caused by

the depletion of oil and natural gas, while the long term need would be to develop

means to replace presently used nuclear fusion technology and then coal. These

conclusions are applicable for India also.

The primary sources of alternative energy which hold potential for

the future can be broadly classified under four categories. These are

1. The solar option.

2. The nuclear option.

3. Tar sands and oil shale.

4. Miscellaneous sources.

2


26/37


Work is in progress in many parts of the world on all these

alternatives.

In the remaining part of this chapter, we shall briefly describe the

various energy alternatives. It is hoped that these descriptions will help the reader

to acquire a broad perspective of the energy problem, before we focus our

attention from the next chapter on wards on the solar energy option and more

specifically direct thermal methods for utilizing solar energy.

The Solar Option :-

Solar energy is a very large, inexhaustible source of energy. The

power from the sun intercepted by the earth is approximately 1.8 X 10 MV,

which is many thousand of times larger than the present consumption rate on the

earth of all commercial energy could supply all the present and future energy

needs of the most promising of the unconventional energy sources.

In addition to its size, solar energy has two other factors in its favor.

Firstly, unlike fossil facts and nuclear power, it is an environmentally clean source

of energy. Secondly, it is free and available in adequate quantities in almost all

parts of the world where people live.

However, there are many problems associated with its use. The

main problem is that it is a dilute source of energy. Even in the hottest regions on

2


27/37


earth, the solar radiation flux available rarely exceeds 1 kwh / m2 and the total

radiation over a day is at best about 7 kwh / m

2

. These are low values from the

point of view of technological utilization . consequently, large collecting areas are

required in many applications and those result in excessive costs.

A second problem associated with the use of solar energy is that its

availability varies widely with time. The variation in availability occurs daily

because of the day-night cycle and also seasonally because of the earths orbit

around the sun. in addition, variations occur at a specific location because of

local weather conditions. Consequently, the energy collected when the sun is

shining must be shored for use during periods when it is not available. The need

for storage also adds significantly to the cost of any system. Thus, the real

challenge in utilizing solar energy as an energy alterative is of an economic nature

methods of collection and storage so that the large initial investments required at

present in most applications per reduced.

A broad classification of the various methods of solar energy

utilization is given in table. It can be seen that the energy from the sun can be

used directly and indirectly. The direct means include the use of water power.

The winds, biomass, wave energy and the temperature difference in the ocean.

30/37


AN ECONOMICAL

1. The cost of shed / roof is totally removal. For 12 x 10 s.q. ft. room the cost

of slap is near about Rs. 10,000/- & for steel roof near about Rs. 2,000/- &

above. The cost multipurpose distillation roof is near about Rs. 18 20

thousand.

2. But :- it gives 40 litre /day & for one month it gives 1200 litre distilled

water in general the cost of distilled water is in bet Rs. 8 10 / litre. So we

save Rs. 96,00/-. Thus we replaced the manufacturing cost of multipurposeDistillation in next 2-3 month only.

The electricity utilized in artificial light source nearly Rs. 432 /- per year.

Which is totally saved by the this instrument.

APPLICATION OF DISTILLED WATER

4) Battery charging & etc.

ADVANTAGES & DISADVANTAGES

3


32/37


MULTIPURPOSE DISTILLATOR

Advantages

1) Life Long Use :-

As the fiber glass can not corrode or deformed in other shape because it

sustain at about 2000 C & no reaction with water or any other aquarium

particles. Also has good strength and it will withstand at 2000 C.

2) Low Maintenance :-

Only for cleaning the water impurities deposited in the term of scale are to

remove there will be some expense then after that there is no maintenance

expenditure.

3) Save Electricity :-

As we required light source in fully packed room currently we are using

electric tubes or bulbs. Thus we can use this instrument in day time then we

can save electricity. And you should know that the rate of electricity per

1000 watt / hr is increases day by day.

4) Use of Unconventional Energy Without Any Uneconomical

Investment :-

We know that the age of sun is more than the earth so the solar energy

source is life long source. And this instrument is not an costly as compared

to other electricity developer instrument.

3


33/37


5) Distilled Water / Pure Water :-

The clouds are from sea water vapor and thus the rain water is pure water.

Hence we can use the Saline water or Hard water in this instrument for

Distilled water / pure water production. As you know that the water for

drinking on earth is only few percentage as compared to whole water on

earth.

6) Cooling Effect :-

The sun rays are firstly transferred from fiber glass & then to water so the

part percentage of solar heat is absorbed by the water and fiber glass

respectively. Thus, we feel cooling effect.

Disadvantages

1) For Indian climate preferable use for 8 to 9 months only ( Oct to May ).

2) High cost of manufacturing as

3

35/37


1. Manhole :- You will use this instrument in wide range then there is a need of

one man hole for cleaning purpose. After prolonged use of maltidistilatar. The

improves and the scales are form in the inner side a instrument which should

be clean per weak.

2. Blow off cock :- There is a need of blow off cock for taking out the muddy

particles and impurities. The blow off cock should be apply at evening, after

sun set.

CONCLUSION

3


36/37


As in future the oil & natural gas will be consumed totally in coming

50 years. It is likely that the production of coal stock will likely to touch maximum

some where between the year 2030 and 2060.

Thus, the future need is to developed the sources of energy for

getting electricity or the replacing instrument.

Hence, this instrument Multipurpose Distillator will be the future

need. Although not for yet but for the future trend it will be an essential.

As it is always said :-

Need is the mother of invention .
