A heat engine operates between two
reservoirs at 782°C and 22°C. One-half of the
work output of the heat engine is used to
drive a Carnot heat pump that removes heat
from the cold surroundings at -8°C and
transfers it to a house maintained at 24°C.
The house is losing heat at a rate of
62,385kJ/h. Determine the power required for the pump in kJ/h unit. Determine the minimum rate of heat supply to the heat engine required to keep the house at 24°C in kW unit.
