Fresh strawberries with a water content of 89.3 percent (by mass) at 26°C are stored in 0.8-kg boxes made of polyethylene (cp = 2.3 kJ/kg · °C). Each box contains 25 kg of strawberries, and the strawberries are to be frozen to an average temperature of 16°C at a rate of 80 boxes per hour. The enthalpy of the strawberries is given to be 367 kJ/kg at 0°C and 54 kJ/kg at 16°C. Taking the average specific heat of the strawberries above freezing temperatures to be cp = 3.94 kJ/kg · °C, determine the rate of heat removal from the strawberries and their boxes.
