A Carnot heat engine receives 15 kW of heat at 1200 K and rejects heat at 300 K.   The power produced from the engine is used to drive a reversed Carnot cycle, acting as a refrigerator, where the low temperature is 260 K and the high temperature is 300 K. What is the cooling effect, the amount of heat removed at 260 K, and what is the COPc ?

Ans:  6.5     73.125 kW

Two Carnot engines function in tandem, such that one rejects heat at a certain temperature, which the other absorbs at the same temperature. Let the first engine be A, and the second B. A intakes 13.4 kW of heat at 530K, and B rejects heat at 270K while doing 2.4kW of work. Determine the power output (work) of engine A.

An experimentalist claims that, based on his measurements, a heat engine receives 300 Btu of heat from a source at 900 R, converts 160 Btu of it to work, and rejects the rest as waste heat to a sink at 540 R. Are these measurements reasonable? Why? Draw a sketch showing the direction of work and of heat transfer between the heat engine and the high and low temperature reservoirs. If the heat engine were to operate reversibly between these...

Chapter 16 Part 2: Question 16.3 An ideal Carnot engine takes 2000 J of heat from a reservoir at 500 K, does some work, and discards some heat to a reservoir at 350 K. Let’s see what happens if the Carnot engine described is run backward as a refrigerator.What is its performance coefficient? SOLUTION SET UP AND SOLVE We know that a refrigerator will act like an engine but with the signs for QH, QC, and Wreversed because the cycle...
