In a production facility, 1.6-in-thick 2-ft x 2-ft square brass plates (p = 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 1500°F at a rate of 300 per minute. If the plates remain in the oven until their average temperature rises to 900°F, determine the rate of heat transfer to the plates in the furnace. 1.6 in Furnace, 1500°F

Question
In a production facility, 1.6-in-thick 2-ft x 2-ft square brass plates (p = 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 1500°F at a rate of 300 per minute. If the plates remain in the oven
until their average temperature rises to 900°F, determine the rate of heat transfer to the plates
in the furnace.
