How fast do raindrops fall?
This question is tricky because some precipitating raindrops may not fall at all, if the surrounding wind has a sufficiently strong upward component.
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.
