Consider a a uniform spherical cloud (diameter 20 cm). The cloud consists of mono dispersed water droplets with diameter dp=100μm. In one sentence, define what terminal velocity is. Calculate the terminal velocity of a single spherical droplet and determine how long it takes for the droplet to reach the floor if travelling from a height of 2 m. You can assume Stokes flow.

Measuring is the comparison of a particular physical quantity with its reference value. A unit is a fixed physical quantity. The length is a physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
