A sphere of ice, 5 cm in diameter, is exposed to 50 km/h wind with 10 percent relative humidity. Both the ice sphere and air are at 21°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 21°C and 90 kPa: D_air-H2O = 2.5 × 10^-5 m²/s³, kinematic viscosity (air) = 1.32 × 10^-7 m²/s, vapor pressure (H₂O) = 0.56 kPa and density (ice) = 915 kg/m³.
