average rain drop size in 20 mm/hr rain

average raindrop diameter | rainfall rate | 20 mm/h (millimeters per hour)

1/(d_av/cm) = 48.5/(R/(mm/h))^(2/9) | | R | rainfall rate d_av | average raindrop diameter

average raindrop diameter | 0.4012 mm (millimeters) = 0.0158 inches = 0.04012 cm (centimeters)

mass | 3.382×10^-5 mg (milligrams) volume | 0.03382 mm^3 (cubic millimeters) terminal velocity | 1.625 m/s (meters per second) terminal Reynolds number | 43 terminal drag coefficient | 1.767 resonant frequency | 1416 Hz (hertz)
