Problem 2 Situation: A heat pump working on a Carnot cycle takes in heat from a reservoir at 5 [C] and delivers heat to a reservoir at 60 [C]. The heat pump is driven by a reversible heat engine which takes in heat from a reservoir at 840 [C] and rejects heat to a reservoir at 60 [C]. The reversible heat engine also drives a machine that absorbs 30 [kW]. Also, the pump extracts 17 [kW] from the 5 [C] reservoir. (Ref.: https://www.youtube.com/watch?v=RxGHzH3HnM8) Requirements: Please determine the following: (a) The rate of heat supply from the 840 [C] source. Ans.: 47.6 [kW] (b) The rate of heat rejection to the 60 [C] sink. Ans.: 34.6 [kW]
