Homework Ch.4-1 Transient heat conduction 1. A dozen approximately spherical apples, 10 cm in diameter are taken from a 30°C environment and laid out on a rack in a refrigerator at 5°C. They have approximately the same physical properties as water, and h is approximately 6 W/m²K as the result of natural convection. a) What will be the temperature of the centers of the apples after 1 hr? b) How long will it take to bring the centers to 10°C? c) How much heat will the refrigerator have to carry away to get the centers to 10°C?
