Reminder these are for ideal conditions and real life results will vary greatly. This calculator is useful for calculating velocities and theoretical pressure loss.
- f = D'Arcy-Weisbach friction coefficient
- Re = Reynolds Number
- dh = hydraulic diameter (m, ft)
- ε = Roughness height, (m, ft)
Average Specific Gravity
Plug in your own values to replace these theoretical values. Specific gravity will vary with temperature.
D'Arcy-Weisbach Friction Coefficient
Average D'Arcy-Weisbach Friction Coefficient for smooth hose, drawn steel tube, aluminum tube with recommended Reynolds numbers.
Ideal sizing would result in velocities between 1 - 4 feet per second. Higher velocities will result in turbulent flow.
