Question

When water is flowing through a pipe with a speed V then its speed V is proportional to?

Answer 1

See an explanation below

Explanation:

This is an open question !!!!

The speed of water is `=Vms^-1`

Suppose the diameter of the pipe is `=dm`

Then the cross sectional area of the pipe is

`A=pi(d^2/4)m^2`

Then the flow rate is

`Q=AV=pi(d^2/4)*Vm^3s^-1`

According to this equation,

`V=(4Q)/(pid^2)`

Therefore,

The speed is proportional to the flow rate.

According to Bernouilli's Equation

`p+rhogz+1/2rhov^2=C`

The velocity is not proportinal to the pressure.
