Answer: Chickens with an average mass of 2.2 kg and

Chapter 5, Problem 5153

(choose chapter or problem)

Chickens with an average mass of 2.2 kg and average specific heat of 3.54 kJ/kg8C are to be cooled by chilled water that enters a continuous-flow-type immersion chiller at 0.58C. Chickens are dropped into the chiller at a uniform temperature of 158C at a rate of 500 chickens per hour and are cooled to an average temperature of 38C before they are taken out. The chiller gains heat from the surroundings at a rate of 200 kJ/h. Determine (a) the rate of heat removal from the chickens, in kW, and (b) the mass flow rate of water, in kg/s, if the temperature rise of water is not to exceed 28C.
