Engine operated between two heat reservoirs at temperatures

Reference no: EM13536862

A Carnot engine is operated between two heat reservoirs at temperatures of 300K and 400K.

a. If the engine recieves 1200kJ from the reservoir at 400K in each cycle, how much heat is transferred to the reservoir at 300K?

b. If the engine is operated as a refrigerator and recieves 1200kJ from the reservoir at 300K, how much heat does it deliver to the reservoir at 400K?

c. How much work is done by the engine in each case?

d. What is the efficiency of the engine and the coefficient of performance of the refrigerator?

e. Sketch a T-S graph for the heat engine.
