heat pump is run by a reversible heat engine operating between reservoirs at 600°C and 40°C. The heat pump working on reversed Carnot cycle picks up 10 kW heat from reservoir at 10°C and delivers it to a reservoir at 40°C. The reversible engine also runs a machine that needs 25 kW. (i) Determine the heat received from highest temperature reservoir and heat rejected to reservoir at 40°C. (ii) Reconsider (i) given that the efficiency of the heat engine and the C.O.P. of the heat pump are each 50 percent of their maximum possible values. Show the arrangement of combined engine-heat pump system.
