Consider 0.8-cm-diameter hail that is falling freely in atmospheric air at 1 atm and 5°C. Determine the terminal velocity of the hail. Take the density of hail to be 910 kg/m3. Take the density and kinematic viscosity of air at 1 atm and 5°C as ρ = 1.269 kg/m3 and v = 1.382 × 10–5 m2/s. The figure for the average drag coefficient for cross-flow over a smooth circular cylinder and a smooth sphere is given below. Find the terminal velocity of the hail:
