I'm really stuck on this problem and I don't know how to go about solving it. 

A central heat pump operating as an air conditioner draws 36000 Btu per hour from a building and operates between the temperatures of 24°C and 38°C.

(a) If its coefficient of performance is 20% that of a Carnot air conditioner, what is the effective coefficient of performance?

(b) What is the power required of the compressor motor? W

(c) What is the power in terms of hp?
