Obtain an expression for the efficiency of an engine in terms of heat derived from source and heat rejected to the sink.

Draw a graph between efficiency and the temperature of the source of a Carnot’s engine, when the sink temperature is constant.

A Carnot engine draws 500 cal of heat from a source at 500K and rejects 300 cal of heat to the sink. Calculate the temperature of the sink and the efficiency of the engine.

In a Carnot engine the temperature of the source and sink are 500 K and 375 K respectively. If the engine consumes 600xx10^3 cal/cycle, find (i) efficiency of the engine
