In a process in which ball bearings are produced, steel ball bearings of .9 cm diameter are quenched by dropping them at a rate of 1000 per minute into an oil-flow cooler and then removing them. The ball bearings are initially 800 deg C and on removal from the oil, are at 35 deg C. Oil flows steadily into the cooler at 15 deg C and leaves at 25 deg C. If heat is also transferred to the cooler from the surroundings (at 15 deg C) at 25o kW, find the rate of heat transfer from the ball bearings and the rate of production of new disorder in this quenching process.
