How do you calculate rain drop velocity?

Use the terminal velocity formula, v = the square root of ((2*m*g)/(ρ*A*C)). m = mass of the falling object. g = the acceleration due to gravity. ρ = the density of the fluid the object is falling through.

Why do rain drops fall with constant velocity?

Rain drop falls with a constant velocity because the weight(which is the force of gravity acting on body) of the drop is balanced by the sum of the buoyant force and force due to friction(or viscosity )of air. Thus the net force on the drop is zero so it falls down with a constant velocity.

What two forces act on a rain drop as it falls?

When a raindrop falls to the surface of the Earth, it is acted on by two main forces, gravity and drag. A stationary raindrop initially experiences an acceleration due to gravity of 9.8 m/s2, as would any falling body.

What is terminal velocity Quora?

Terminal velocity is the point of time when a body undergoing free fall reaches a point where the force due to gravity i.e the the body’s weight is equal to air resistance or friction. Hence its velocity will no longer change and it has reached terminal velocity.

How do I calculate terminal velocity?

Use the terminal velocity formula, v = the square root of ((2*m*g)/(ρ*A*C)).

1. m = mass of the falling object.
2. g = the acceleration due to gravity.
3. ρ = the density of the fluid the object is falling through.
4. A = the projected area of the object.
5. C = the drag coefficient.

When a rain drop falls down the weight of the rain drop is balanced by?

Originally Answered: When a raindrop falls through the atmosphere the weight of the raindrop is balanced by the viscous force and buoyant force and it falls by zero acceleration.

What is the speed of falling rain?

When all the parameters are considered the terminal velocity of a typical raindrop is calculated to be about 9 meters per second or 20 mph. A smaller raindrop of radius 0.15 cm has a terminal velocity of about 7 meters per second or 16 mph.

Which force is responsible for rainfall?

For example, gravitational force of attraction of earth is responsible for binding all terrestrial object on earth. The same force is responsible for holding the atmosphere around earth, for rainfall and snowfall on earth.

What is proportional force?

Force is directly proportional to acceleration (force ~ acceleration)

How do you find terminal velocity with mass?

What is the acceleration of a raindrop while falling down?

At that stage, the net force on the raindrop is zero and consequently, the acceleration is zero. The forces acting on a raindrop while falling down are-1. Its weight, W=mg and 2. Air resistance, R=kv^2, where v is the speed of the drop and k is a constant.

Why is the net force of a rain drop zero?

As the speed is uniform and not changing, the acceleration is zero. This means that the net force will be zero too. A rain drop of mass 2 gm falls from a height of 1 km. It hits the ground with the speed of 50 m/s.

What is the speed of a drop of rain water?

Consider a drop of rain water having mass 1g falling from a height of 1km. It hits the ground with a speed of 50m/s. Take ‘ g ‘ constant with a value 10m/s 2.

What is the work done by a raindrop of 1g fall?

A raindrop of mass 1 g falling from a height of 1 km hits the ground with a speed of 50 ms^-1 . If the resistive force is proportional to the speed of the drop, then the work done by the resistive force is (Take g = 10 ms^-2) . > A raindrop of mass 1 g fall…
