The First Look at Manufacturing Process

• The main purpose of manufacturing processes is to transform materials into useful products.

During any Manufacturing operation, energy resource(s) are consumed.

This alerts the usefulness of material resources.

The Accounting : A major concern in Extrasomatism

• If we are living in a cave and realized our extrasomatism, we need to start accounting with some degree of precise standard.

• We might be having fire, stick and stone tools in our cave.

• There, starts a measurement system.

• Like when you grunt and say how many beast you killed for dinner, 1, 2 or 3.....measurements.

• When gathering wood for a fire you would ask for so much wood.....measurement.

• To live in our physical world we need to understand it (The Knowledge).

Innovation and Conservation

Definition of Thermodynamics

• Thermodynamics is defined as the science of energy.

• The name Thermodynamics stems from the Greek words therme (Heat) and dynamics (Power).

– Clearly depicting the early efforts to convert heat into power.

Definition of Engineering Thermodynamics

• Engineering Thermodynamics is the subject that deals with the study of the science of thermodynamics and the usefulness of this science in the design of each & every process, device or system involving the effective utilization of energy and matter for the benefit of mankind.

• The Trio of Thermodynamics : Heat, Work & Energy.

• Matter playing the role of a House.
