# Pipe Flow Velocity Calculator, Formula, Pipe Flow Velocity Calculation

## Pipe Flow Velocity Calculator:>

Enter the values of constant  k , Roughness coefficient C , Hydraulic radius R(m) & Slope of the pipe S to determine the value of Pipe Flow Velocity v(m/s).

 Enter Roughness Coefficient: Enter Hydraulic Radius: Enter Slope of the pipe: Result – Pipe Flow Velocity: m/s

## Pipe Flow Velocity Formula:

The Pipe Flow Velocity v(m/s) in meter per second is equal to the ( k ) is a constant and multiply the Roughness coefficient ( C ) and multiply the Hydraulic radius R(m) in meter and again multiply the Slope of the pipe ( S ).

The formula of Pipe Flow Velocity can be writtern as,

v(m/s) = k * C * R0.63(m) * S0.54

Here,

v(m/s) = Pipe Flow Velocity in meter per second

k = constant value of .849

C = Roughness coefficient

R(m) = Hydraulic radius in meter

S = Slope of the pipe

### Calculation for Pipe Flow Velocity:

1)Determine the Pipe Flow Velocity and given for k = .849 , C = 1.225 , R = 4m , S = 5

Answer

v = k * C * R0.63 * S0.54

v = .849 * 1.225 * 40.63 * 50.54

v = 5.93m/s.

2)Determine the Slope of the pipe  and given for k = .849 , C = 1.225 , R = 4m , Pipe Flow Velocity = 5.93m/s.

Answer

v = k * C * R0.63 * S0.54

5.93 = .849 * 1.225 * 40.63 * S

S = 5.
