10.) A typical one-half-carlot-capacity banana room contains 18 pallets of bananas.Each pallet consists of 24 boxes, and thus the room stores 432 boxes of bananas. A box holds an average of 19 kg of bananas and is made of 2.3 kg of fiberboard. The specific heats of banana and the fiberboard are 3.55 kJ/kg · C and 1.7 kJ/kg · C, respectively. The peak heat of respiration of bananas is 0.3 W/kg. The bananas are cooled at a rate of 0.2 C/h. If the temperature rise of refrigerated air is not to exceed 1.5 C as it flows through the room, determine the minimum flow rate of air needed. Take the density and specific heat of air to be 1.2 kg/m3 and 1.0 kJ/kg · C.
