A heat pump with a coefficient of performance of 38

A heat pump with a coefficient of performance of 3.8 provides energy at an average rate of 75,000 kJ/h to maintain a building at 21^oC on a day when the outside temperature is 0^oC. If electricity costs 8 cents per kW. h.

Determine the electric power required by the heat pump, in kJ/h.

Determine the daily cost of running the heat pump if the cost of electricity is $0.08 per kW · hr.

Determine the maximum coefficient of performance for the given temperatures.

Determine the minimum theoretical power required by the heat pump, in kJ/h.
