A heat pump working on the 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 forgives a machine that absorbs 30 kW. If the heat pump extract 17 kJ/s from
the 5°C reservoir, determine :
a) The rate of heat supply from the 840°C source
b) The rate of heat rejection to the 60°C sink.
