During air cooling of oranges, grapefruit, and tangelos, the heat transfer coefficient for combined convection, radiation, and evaporation for air velocities of 0.11 < V<0.33 m/s is determined experimentally and is expressed as h = 5.05 kair Re 1/3/D, where the diameter D is the characteristic length. Oranges are cooled by refrigerated air at 3°C and 1 atm at a velocity of 0.3 m/s. The thermal conductivity of the orange is given to be k= 0.70 W/m.°C. The thermal conductivity and the kinematic viscosity of air at the film temperature of (Ts + Too)/2 = (15+3)/2 = 9°C are k= 0.02431 W/m.°C and v= 1.417 x 10-5 m2/s, respectively. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air 3°C 1 atm 111111 Orange Determine the initial rate of heat transfer from a 0.12-m-diameter orange initially at 15°C with a thermal conductivity of 0.7 W/m.K. The initial rate of heat transfer is 3.6 W.
