Brass balls, each of mass 0.258 kg, and initially at 130°C, are quenched in a water bath at 50°C for 2 minutes at a rate of 120 balls per minute. After quenching, the temperature of the balls drops to 76°C. If the specific heat of brass (C) is 0.385 kJ/kg.K, determine the rate at which heat needs to be removed from the water in order to keep its temperature constant at 50°C.
