In a foundry, metal castings are cooled by quenching in an oil bath. Typically, a casting weighting 20 kg and at a temperature of 450 oC is cooled by placing it in a 150 kg in volatile oil bath initially at 50 oC. If the specific heat capacity of the metal is 0.5 J/kg K, and that of the oil is 2.6 J/kg K, determine the entropy change in this process and the common final temperature of the oil and the casting after quenching. Assume that there are no heat losses
