Chickens with an average mass of 2.2 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 250 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 25°C at a rate of 150 kJ/h. Determine
(a) The rate of heat removal from the chickens, in kW, and
(b) The rate of entropy generation during this chilling process.
