Pump sizing calculator
A free pump sizing calculator for total dynamic head. Enter the static lift, the pressure and velocity heads and the pipe run, and the app builds the duty point you need to specify, with the friction and fitting losses broken out so you can see where the head is going.
What the pump sizing calculator works out
Pump Sizing is deliberately narrow: it solves one sizing problem completely, with the assumptions written down next to the result.
- Total dynamic head
- with every component listed, so a reviewer can follow the number.
- Pipe friction loss
- by Darcy-Weisbach, with the friction factor from the pipe material and flow.
- Fitting losses
- bends, valves and entries and exits through their K factors.
- Velocity and pressure head
- from the flow rate, the pipe bore and the system pressures.
- Custom fluids
- density and viscosity other than water, at your working temperature.
Typical jobs
- Pressure, velocity and elevation head breakdown
- Custom fluids and multi-material pipe roughness
- Booster set and transfer pump duty points
- Irrigation and drainage system head loss

Pump Sizing for Android
The Android app computes the numerical total dynamic head with the full loss breakdown, handles custom fluids and pipe materials, and generates the calculation report, offline. No account, no sign-in, no data connection.
