A heat pump is working on the carnot cycle takes in heat from a reservoir at 5 oc and delivers heat to a reservoir at 60oc. The heat pump is driven by a reversible heat engine which takes in heat from a reservoir at 840oc and rejects heat to a reservoir at 60oc. The reversible heat engine also drives a machine that absorbs 30 kw. If the heat pump extracts 17 kj/s from the 5 oc reservoir, determine
a.The rate of heat supply from the 840oc source
b.The rate of heat rejection to the 60oc sink.
