Chickens with an average mass of 1.6 kg and average specific heat of 3.54 kJ/kg*C are to be cooled by chilled water that enters a continuous-flow-type immersion chiller at 0.5 C and leaves at 2.5 C. Chickens are dropped into the chiller at a uniform temperature of 15 C at a rate of 700 chickens per hour and are cooled to an average temperature of 3 C before they are taken out. The chiller gains heat from the surroundings at a rate of 400 kJ/h. Determine the rate of exergy destruction during the chilling process. Take T0=25 C.
