An irreversible heat pump with COP of 2.4 is used to heat water to 80°C for cleaning (b) purposes. This heat pump absorbs heat from surrounding at 30°C and received the entire power, W from a Carnot heat engine operating between 250°C and 30°C. The Carnot heat engine received 6.3 kW of heat from the high temperature source. i) Draw the schematic diagram of the above system. ii) Determine the power received by the heat pump, W from Carnot heat engine, kW. iii) Calculate the rate of heat supplied to the water by the heat pump, kW. iv) Determine the COP of the heat pump if it operates on a reversed Carnot cycle.

Question
(b) An irreversible heat pump with COP of 2.4 is used to heat water to 80°C for cleaning
purposes. This heat pump absorbs heat from surrounding at 30°C and received the entire
power, W from a Carnot heat engine operating between 250°C and 30°C. The Carnot heat
engine received 6.3 kW of heat from the high temperature source.
i) Draw the schematic diagram of the above system.
ii) Determine the power received by the heat pump, W from Carnot heat engine, kW.
iii) Calculate the rate of heat supplied to the water by the heat pump, kW.
iv) Determine the COP of the heat pump if it operates on a reversed Carnot cycle.
