Pipe Contraction Friction Loss Under Partial Flow Calculator

Partial Flow Pipe Contraction Friction Loss Calculator

Calculate the friction loss in a pipe contraction under partial flow using:
\[ h_f = K_{cp} \frac{V^2}{2g} \]

* Enter the contraction loss coefficient for partial flow \(K_{cp}\) and the flow velocity \(V\) (ft/s).

Step 1: Enter Parameters

Partial Flow Contraction Loss Coefficient, \(K_{cp}\):

Example: 0.7

Flow Velocity, \(V\) (ft/s):

Example: 12 ft/s
