Tubing friction
Calculates Hazen-Williams tubing friction loss from flow rate, tubing ID, tubing length, and roughness coefficient.
Calculate tubing friction
Enter flow, tubing ID, length, and Hazen-Williams C to compute friction loss.
Hazen Williams Friction Coefficient
| Type Tubing | New Tubing | Recommended Mid Life Tubing (10 Year) | Old Tubing (20 Year) | Excessive Scale, Corrosion Pitting etc. |
|---|---|---|---|---|
| Metal | 130 - 140 | 110 - 120 | 90 - 100 | 80 - 90 |
| Plastic (PVC) | 130 - 150 | 110 - 130 | 100 - 110 | 90 - 100 |
Hazen-Williams roughness coefficient.
m3/D
Flow-rate unit selector.
Water or liquid flow rate in the selected unit.
Accepted for workflow context; the H&W friction loss output does not use it.
Millimeters
Unit for Tubing ID.
Internal diameter of tubing.
Feet
Unit for tubing length.
Length of tubing in selected unit.
