Hazen-Williams Imperial Head Loss Analyst
Calculate friction head loss, pressure drop, and fluid velocity across imperial water distribution pipelines.
Hazen-Williams Imperial Equation:
\( h_{100\text{ft}} = 0.2083 \times \left(\frac{100}{C}\right)^{1.852} \times \frac{Q^{1.852}}{d^{4.8655}} \)
Where flow rate is in GPM, pipe inside diameter is in inches, and friction loss is in feet of head per 100 feet of pipe length.
Pipeline Parameters
Default: 2" Schedule 40 Steel / PVC (2.067" ID)
Total Head Loss
11.45 ft
Friction Pressure Drop
4.96 PSI
Fluid Velocity
4.78 ft/s
Velocity Threshold Status Check
Fluid velocity is within safe erosion-free operating limits (2.0 ft/s to 10.0 ft/s).
