Transcribed Image Text:Problem 4-Carnot Heat Engine (
A Carnot heat engine operates between a source at 600°C and a sink at 300°C. Please answer
the following.
a. What is the temperature of the isothermal processes in the Carnot cycle? Why? Justify
your answer.
b.
Compute the thermal efficiency.
c. The source supplies steadily 20 kW to the engine operating as a Carnot heat engine.
Compute the heat transferred to the sink, express your answer with the correct units for
this problem.
d. Now, you are ready to verify a claim from a heat engine owner related to a heat engine
that operates between the same thermal reservoirs you used for the Carnot engine. The
owner has been told by the inventor that the engine can produce 15 kW while rejecting
10 kJ/s to a sink. Is this claim valid? Justify your answer. Would you buy this engine?
