QUESTION:
A completely reversible heat engine operates with a source at and a sink at . If the entropy of the sink increases by , how much will the entropy of the source decrease? How much heat, in Btu, is transferred from the source?
ANSWER:
Step 1 of 3
The source and sink temperatures and the entropy change of the sink for a completely reversible heat engine are given. Refer to the figure below.
The entropy decrease of the source and the amount of heat transfer from the source are to be determined.
We assume that the heat engine operates steadily.
