a) A reversible heat pump cycle operates between a cold reservoir at 300ºC and a hot reservoir at 500ºC. Determine the coefficient of performance.

b) Is it possible for a heat engine to operate on a cycle with an efficiency of 0.5 between reservoirs at 100ºC and 400ºC?

c) Two reversible heat engines operate between the same two thermal reservoirs. Heat engine A has a thermal efficiency of 0.42. Heat engine B has a heat input rate of 100 kW. Determine the power output of heat engine B.

d) A window unit can function as either an air conditioner or a heat pump. While acting as an air conditioner the unit can remove 3 kW of heat while using 600 W of electrical power. What is the coefficient of performance when the unit acts as a heat pump?
