A sphere of ice, 5 cm in diameter, is exposed to 65 km/h wind with 15 percent relative humidity. Both the ice sphere and air are at ? 1°C and 90 kPa. Predict the rate of evaporation of the ice in g/h by use of the following correlation for single spheres: Sh = [4.0 + 1.21 (ReSc)2/3]0.5. Data at ? 1°C and 90 kPa: , kinematic viscosity (air) = 1.32 × 10?7 m2/s, vapor pressure (H2O) = 0.56 kPa and density (ice) = 915 kg/m3.
