As we know that;
The efficiency of Carnot engine is,
= e= 0.65
So, the engine were run backward as heat pump then coefficient of performance is,
Then,
= (COP)heat= 1/e
=(COP)heat=1/0.65
= (COP)heat= 1.5384
= (COP)heat=1.54......Answer

Chapter 15, Problem 012 Your answer is partially correct. Try again. The volume of a gas is changed along the curved ine between A and B in the drawing. Do not assume that the curved line is an isotherm or that the gas is ideal. What is the work done for the process? 2.0 10* Pa Volume 20.10 Untd 3100 the tolerance is +14%
