Rain drop terminal velocity

WebbWith the obtained wind flow patterns, rain drop trajectories are calculated for rain drop diameters from 0.5 to 6 mm. Rain drops are injected from a horizontal plane located in the upstream-undisturbed wind flow, high above the ground: its location must allow injected rain drops to reach the terminal fall velocity (vertical) and wind WebbA smaller raindrop of radius 0.15 cm has a terminal velocity of about 7 meters per second or 16 mph. In general, depending upon their size, raindrops fall between 15 and 25 miles …
