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, rho = 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 at the ball bearing surface at a given instant during the quenching process is 50 k/s.
