It is proposed that a cyclic heat engine be constructed to operate in the ocean at a location where the water temperature is 20 °C near the surface and 5 °C at some greater depth. What is the maximum possible thermal efficiency of such an engine?

It is proposed that a cyclic heat engine be constructed to operate in the ocean at a location
where the water temperature is 20 °C near the surface and 5 °C at some greater depth. What
is the maximum possible thermal efficiency of such an engine?
A heat pump is used to maintain a heated space at 22 °C by extracting heat from outdoor air
on a day when the air temperature is 0 °C. Determine the maximum COP that the heat pump
can achieve under these circumstances.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fef4abb29-973a-44d3-9b2d-c4032542ce74%2F8bbc2862-1faf-4bf1-b86c-edd34b786980%2F0xjsvqe_processed.png&w=3840&q=75)
