It is desired to predict the heat transfer coefficient (use the formula found in Perry’s handbook;use SI system) for air being blown past an apple lying on a screen with large openings. The airvelocity is 0.61 m/s at 101.32 kPa pressure and temperature 288.75 K having a thermalconductivity of 0.02492 W/m·K. The surface of the apple is at 355.35 K and its averagediameter is 114 mm. Assume that it is an isothermal sphere with the following properties: ρ =1.097 kg/m3, μ = 1.95x10-5 Pas, NPr = 0.70
