Question

Estimate the speed of vertically falling raindrops from the following data. Radius of the drops = 0.02 cm, viscosity of air = 1.8 × 10-4 poise, g = 9.9 × 10 m s-2 and density of water = 1000 kg m-3.<br />no spamming

Answer 2

Explanation:

An air bubble of radius 1mm moves up with uniform velocity of 0.109ms

−1

in a liquid column of density 14.7×10
