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).

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 * R^0.63_(m) * S^0.54

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 * R^0.63 * S^0.54

v = .849 * 1.225 * 4^0.63 * 5^0.54

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 * R^0.63 * S^0.54

5.93 = .849 * 1.225 * 4^0.63 * S

S = 5.
