Aluminum components at 480C are cooled rapidly by quenching them in a refrigerated brine bath maintained at -20C. The bath is fed with brine into aluminum pieces at a rate of 1 kg/min. The refrigerated bath rejects heat in the environment at 30C. What is the theoretical power required what must the motor have (in kW) to operate this cooling bath? For aluminium: Cp = 28 J/K-mole P.M.=27g/mole Rep.: 1.7 kW
