In a chicken processing plant, whole chickens averaging 5 lbm each and initially at 65°F are to be cooled in the racks of a large refrigerator that is maintained at 5°F. The entire chicken is to be cooled below 45°F, but the temperature of the chicken is not to drop below 35°F at any point during refrigeration.

The convection heat transfer coefficient and thus the rate of heat transfer from the chicken can be controlled by varying the speed of a circulating fan inside. Determine the heat transfer coefficient that will enable us to meet both temperature constraints while keeping the refrigeration time to a minimum. The chicken can be treated as a homogeneous spherical object having the properties ρ = 74.9 lbm/ft3 ,

cp = 0.98 Btu/lbm·°F, k = 0.26 Btu/h·ft·°F, and α = 0.0035 ft2 /h. Solve this problem using the Heisler charts. Transient Heat Conduction in Semi-Infinite Solids
