A spherical water droplet of 1.5 mm diameter is freely falling in atmospheric air. Calculate the average convection heat transfer coefficient when the droplet has reached its terminal velocity. Assume that the water is at 50?C and the air is at 20?C. Neglect mass transfer and radiation.GIVENA spherical water droplet freely falling in atmospheric airDrop diameter (D) = 1.5 mm = 0.0015 mWater drop temperature (Td) = 50?CAir temperature (T??) =20?C
