Referring to Problem 1.65, how many kilograms of ice can a 3-ton refrigeration unit produce in a 24-hour period? The heat of fusion of water is 330 kJ/kg. From Problem 1.65: A manufacturer in the U.S. wants to sell a refrigeration system to a customer in Germany. The standard measure of refrigeration capacity used in the United States is the ‘ton’; a one-ton capacity means that the unit is capable of making about one ton of ice per day or has a heat removal rate of 12,000 Btu/hr. The capacity of the American system is to be guaranteed at three tons. What would this guarantee be in SI units?
GIVEN

Heat of fusion of ice is 330 kJ/kg
ASSUMPTIONS
(a) Water is cooled to just above the freezing point before entering the unit
