Question:

In a manufacturing plant, a quench hardening process is used to treat steel ball bearings (c = 500 J/kg·K, k = 60 W/m·K, r = 7900 kg/m3) of 25 mm in diameter. After being heated to a prescribed temperature, the steel ball bearings are quenched. Determine the rate of heat loss if the rate of temperature decrease in the ball bearing at a given instant during the quenching process is 50 K/s.
