In a manufacturing facility, 5-cm-diameter brass balls
Chapter 4, Problem 88P(choose chapter or problem)
In a manufacturing facility, \(5-\mathrm{cm}\)-diameter brass balls \(\left(\rho=8522 \mathrm{~kg} / \mathrm{m}^{3}\right.\) and \(\left.c_{p}=0.385 \mathrm{~kJ} / \mathrm{kg} \cdot{ }^{\circ} \mathrm{C}\right)\) initially at \(120^{\circ} \mathrm{C}\) are quenched in a water bath at \(50^{\circ} \mathrm{C}\) for a period of \(2 \mathrm{~min}\) at a rate of 100 balls per minute. If the temperature of the balls after quenching is \(74^{\circ} \mathrm{C}\), determine the rate at which heat needs to be removed from the water in order to keep its temperature constant at \(50^{\circ} \mathrm{C}\).
