Stainless stell ball bearings (desity = 8085 kg/m^3 and Cp = 0.480 kJ/(kg*C) ) having a diameter of 1.2 cm are to be quenched in water at a rate of 800 per minute. The balls leave the oven at a uniform temperature of 900 degrees Celcius and are exposed to air at 25 degrees celcius for a while before they are dropped into the water. If the temperature of the balls drops to 850 degrees celcius propr to quenching, determine the rate of heat transfer from the balls to the air.
