An ice maker operating at steady state makes ice from liquid water at 32°F. Assume that 144 Btu/lb of energy must be removed by heat transfer to freeze water at 32°F and that the surroundings are at 79.0°F. The ice maker consumes 1.4 kW of power. Determine the maximum rate that ice can be produced, in Ib/h, the corresponding rate of heat rejection to the surroundings, in Btu/h, and the maximum coefficient of performance of the cycle.

An ice maker operating at steady state makes ice from liquid water at 32°F. Assume that 144 Btu/lb of energy must be removed by
heat transfer to freeze water at 32°F and that the surroundings are at 79.0°F. The ice maker consumes 1.4 kW of power.
Determine the maximum rate that ice can be produced, in Ib/h, the corresponding rate of heat rejection to the surroundings, in Btu/h,
and the maximum coefficient of performance of the cycle.
