A refrigeration machine rejects QH = 680 Btu per cycle to a hot reservoir at TH = 540°R, while receiving Qc = 483.0 Btu per cycle from a cold reservoir at temperature Tc. The machine operates at 10 cycles per minute. Determine the net power input, in hp, the minimum theoretical temperature Tc, in °R, and the maximum coefficient of performance of the cycle.
