Question

6) A reversible engine is supplied with heat from two constant temp. source at
900 K and 600 K and rejects heat to a sink at 300 K. Assuming the engine
executes a number of complete cycles, while develop 70 KW and rejecting
3200 kJ/min. Calculate the heat supplied by each source and efficiency of
the engine.

Answer 1

Answer:

A reversible heat engine receives 2 kJ of heat from a reservoir at 1000 K and a certain amount of heat from a reservoir at 800 K. It rejects 1 kJ of heat to a reservoir at 400 K. The net work output (in kJ) of the cycle is 1.4
