Question

velocity of flow of water in a horizontal pipe is 10.0 metre per second find the velocity minus head or water​

Answer 1

Dear student

Velocity head = V²/2g

Hence if g = 10m/sec²

Velocity head = 10²/2*10 = 5 m

Answer 2

The head velocity is 5.10 m/s.

Explanation:

Given that,

Initial velocity = 10.0 m/s

We need to calculate the head velocity

Using formula of head velocity

$v_{h}=\dfrac{u^2}{2g}$

Where, u = initial velocity

g = acceleration due to gravity

Put the value into the formula

$v_{h}=\dfrac{10.0^2}{2\times9.8}$

$v_{h}=5.10\ m/s$

Hence, The head velocity is 5.10 m/s.
