1) A retort and 2000 cans of tuna fish have been heated to a uniform temperature of 116C. It is desired to cool the cans to 35C before removing them form the retort. How much cooling water is required if it enters the retort at 20C and leaves at 30C?. Given Cp of tuna fish = 3.65 kJ/kg/C Cp of can wall = 0.46 kJ/kg/C Cp of water 4.18 kJ/kg/C = Mass of tuna fish/can = 450 g Mass of can wall/can = 55 g Energy required to cool retort = 75000 kJ 1) A retort and 2000 cans of tuna fish have been heated to a uniform temperature of 116C.
