A still retort containing 1,000 cans of apple sauce was sterilized at 121°C. After sterilization, the cans need to be cooled down to 37°C before leaving the retort. The specific heats of the apple sauce and the can metal are 3730 and 510 J/kg-K, respectively. Each can weigh 50 g and contains 450 g of apple sauce. The retort wall is made of cast iron and weighs 3,000 kg. it is assumed that cooling by the surrounding air is negligible. Calculate the amount of cooling water required if it enters at 20°C and leaves at 30°C.
