Its difficult to give an exact figure as the height at which raindrops fall and their size vary widely, but given that raindrops fall at an average speed of around 14 mph and assuming a cloud base height of around 2,500 feet, a raindrop would take just over 2 minutes to reach the ground.

How fast was the fastest raindrop?
In still air, the terminal speed of a raindrop is an increasing function of the size of the drop, reaching a maximum of about 10 meters per second (20 knots) for the largest drops.

Can large rain drops fall at speeds of 20 mph?
A large raindrop, about one-quarter of an inch across or about the size of a house fly, has terminal fall speeds of about 10 meters per second or about 20 mph. That kind of speed can cause compaction and erosion of the soil by the force of impact.

How many raindrops fall per second?
This means that 1/3600 inches (0.0254 m / 3600) of rain would fall per second. This means that 7.1 E – 7 meters of rain would hit the area in one second.

What is the highest speed of rain?
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.

How fast does a rain drop fall?
In still air, the terminal speed of a raindrop is an increasing function of the size of the drop, reaching a maximum of about 10 meters per second (20 knots) for the largest drops. To reach the ground from, say, 4000 meters up, such a raindrop will take at least 400 seconds, or about seven minutes.

What is the biggest a rain drop can be?
Drops vary in size from the tiny cloud droplets (measuring less than 0.1 mm in diameter) to the large drops associated with heavy rainfall, and reaching up to 6 mm in diameter.

How much rain drops per second?
description and formation. Considerable growth of the cloud droplets (with falling speeds of only about 1 cm, or 0.4 inch, per second) is therefore necessary if they are to fall through the cloud, survive evaporation in the unsaturated air below, and reach the ground as drizzle or rain.

How many raindrops fall during a rainstorm?
As the 7.6mm were only a lower bound, we can say that there are at least 200,000 drops per square meter and hour in a heavy rain, but typically a lot more (as in, several millions).
