Which falls faster , big rain drops or small rain drops ?

Text Solution

Verified by Experts

Terminal velocity of rain drop ,
`v_(t)=(2)/(9)r^(2)g((rho-sigma)/(eta))`
`therefore` According to `v_(t)propr^(2)`,
large drop have more terminal velocity so , it falls quickly.

A person is walking to the east at 2 km/hr and the rain drops appear to him dropping vertically downwards at 2sqrt(3)km//hr . Find the actual velocity of rain.

Why raincoat does not wet in rain ?

A glass wind screen whose inclination with the vertical can be changed is mounted on a car. The moves horizontally with a speed of 2m//s . At what angle alpha with the vertical should the wind screen placed so that the rain drops falling vertically downwards with velcoity 6m//s strike the wind screen perpendicularly?

By the term velocity of rain, we mean velocity with which raindrops fall relative to the ground. In absence of wind, raindrops fall vertically and in presence of wind raindrops fall obliqucly. Moreover raindrops acquire a constant terminal velocity due air resistance very quickly as they fall toward the carth. A moving man relative to himself observes an altered velocity of raindrops. Which is known as velocity of rain relative to the man. It is given by the following equation. vec(v)_(rm)=vec(v)_(r)-vec(v)_(m) A standstill man relative to himself observes rain falling with velocity, which is equal to velocity of the raindrops relative to the ground. To protect himself a man should his umbrella against velocity of raindrops relative to himself as shown in the following figure. Rain is falling vertically with velocity 80 cm/s. (a) How should you hold your umbrella ? (b) You start walking towards the east with velocity 60 cm/s. How should you hold umbrella ? (c) You are walking towards the west with velocity 60 cm/s. How should you hold your umbrella ? (d) You are walking towards the north with velocity 60 cm/s. How should you hold your umbrella? (e) You are walking towards the south with velocity 80 cm/s. How should you hold your umbrella ?

Sixty four spherical rain drops of equal size are falling vertically through air with a terminal velocity 1.5ms^(-1) . If these drops coalesce to form a big spherical drop, then terminal velocity of big drop is:

It is a common observation that rain clouds can be at about a kilometer altitude above the ground. (a) If a rain drop falls from such a height freely under gravity, what will be its speed? Also calculate in km/h (g = 10 m//s^(2) ). (b) A typical rain drop is about 4 mm diameter. Momentum is mass x speed in magnitude. Estimate its momentum when it hits ground. (c) Estimate the time required to flatten the drop. (d) Rate of change of momentum is force. Estimate how much force such a drop would exert on you. (e) Estimate the order of magnitude force on umbrella. Typical lateral separation between two rain drops is 5 cm. (Assume that umbrella is circular and has a diameter of 1 m and cloth is not pierced through.)

The energy would be …. If 1 large drop of water drop splitting into 8 small drop of water.
