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. chickens are dropped into the chiller at a uniform temperature of 15°c at a rate of 500 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 200 kj/h.

determine :

(a) the rate of heat removal from the chicken, in kw, and

(b) the mass flow rate of water, in kg/s, if the temperature rise of water is not to exceed 2°c.
