Population DensityCalculation of total number of residents:

1. Normal Increase ( using equations)

Example:- Total Area of Southern Remal = 2,754 Dounm

- Total population in Southern Remal in 2002 = 17,500

- Total population in Southern Remal in 2008 = 29,300

Population Density2. Saturation populationTotal Residential Area = 519,917 m2

Total number of population under saturation condition = 45,721 + 59,918 = 105,639

Population DensityTherefore,Population density= Population / Total Area

= 99,435 / 641,000 = 0.155 person/m2

For your project use the following

data;Total Area of Southern Remal = 2,754 Dounm

Total population in Southern Remal in 2002 = 17,500 inh.

Total population in Southern Remal in 2008 = 29,300 inh.

Regular buildings,

# of stories = 5

apartment area = 150 m2

# of family members = 7

Population density = ??!!

Allocation steps:Draw network layout for the target year and pinpoint junctions

and pipelines.Draw areas around the nodes in a way that cover the entire area

under consideration.Determine the water demand type of each junction using the land

use map prepared and determine the areas that are served by each junction.

Calculate the number of population served by each junction (using the area and the density)

Calculate the demand of each junction by multiplying the population by the average consumption per capita.

Specify other types of demand and allocate them to the nearest nodes.

The demand of each junction should be multiplied by a coefficient accounts for UFW in the design year.

Example:
