How fast does rain fall?

Question
How fast does rain fall?

Answer

The speed of rain depends on the size of the raindrop. The smallest “drizzle” droplets—with diameters less than .02 inch—fall at 1 to 4 mph. Raindrops with diameters greater than 0.02 inch fall faster—from about 5 to 20 mph; the average fall speed is 14 mph.
