Paper Details

In a production facility, 1.2-in-thick, 2-ft = 2-ft square brass plates (r = 532.5 lbm/ft3 and cp = 0.091 Btu/lbm ? °F) that are initially at a uniform temperature of 75°F are heated by passing them through an oven at 1300°F at a rate of 300 per minute. If the plates remain in the oven until their average temperature rises to 1000°F, determine the rate of heat transfer to the plates in the furnace and the rate of energy destruction associated with this heat transfer process.
