Calculate the ideal power in kW to make 1 Ton (=1000 kg) of ice
at 0 deg.C per hour from water at 20 deg.C. Surroundings at 20
deg.C.
Use the expression for Wideal to calculate the power.
The total enthalpy change of the water = [(enthalpy change of the
water cooled from 20 to 0 deg.C) + (enthalpy change of water to ice
at 0 deg.C, this is the heat of fusion of water)].
The total entropy change of the water = [(entropy change of water
cooled from 20 to 0 deg.C) + (entropy change of ice at 0 deg.C =
(heat of fusion of water)/(temperature of fusion of water to ice)].
You can find enthalpy and entropy changes of the water from a steam
table. Be sure to keep the signs of the terms correct. The answer
is about 12 kW.
