Repeat Prob. 4–74 for aluminum balls.

Prob. 4–74

In a manufacturing facility, 5-cm-diameter brass balls (p= 8522 kg/m3 and cp 0.385 kJ/kg · °C) initially at 120°C are quenched in a water bath at 50°C for a period of 2 min at a rate of 100 balls per minute. If the temperature of the balls after quenching is 74°C, determine the rate at which heat needs to be removed from the water in order to keep its temperature constant at 50°C.
