Question

Co-efficient of performance for a reversed Carnot cycle working between temperatures T1 and T2 (T1 > T2) is ___________________?

Accepted Answer

T2/(T1 – T2). The COP for a reversed Carnot cycle is given by the ratio of the cold reservoir temperature to the difference between the hot and cold temperatures.
