Question

Why do we see rain fall in drops and not as water flows though pipe?

Answer 1

Because of water's molecular structure. When it rains very hard one can actually see the rain as stripes and not as drops.

Have you ever seen a single drop of water falling on a pond?

Have you ever seen water in a glass, filled to the top? It makes a little round curve if you keep on adding water slowly just before it overflows. Same reason - molecular structure.

Answer 2

Much the same idea why condensation on a window forms droplets. The water vapour condenses at a point and when the mass of the water droplet is too heavy for the up-draft air to support it, it falls from the sky.

IF the number of droplets per second per cm were big enough you may have water falling like from a pipe. TORRENTIAL rainstorms approach this. If it did happen however, the likelihood is that we would drown since no atmospheric gases would be available.

Answer 3

Rain is condensed water vapor (Cloud) on heat exchange surface (dust).There are two types of condensation on heat exchanger surfaces

1-drop condensation

2-film condensation

both depend on the physical property  of the exchanger.In case of rain it is drop condensation . hope that explain

Answer 4

surface tension....

Answer 5

air resistance
