Which one do you need?
- Pipe Volume Calculator
- Find how many gallons a pipe holds from its inside diameter and length. Get volume in gallons, liters and cubic feet, gallons per foot and water weight.
- Pipe Water Velocity Calculator
- Convert GPM and pipe size to water velocity in ft/s and m/s, and check the result against the erosion limits used for copper, PEX, steel and PVC piping.
- Hazen-Williams Flow & Head Loss Calculator
- Solve the Hazen-Williams equation for flow, head loss or pipe diameter. Enter C factor, bore and length to get psi per 100 ft, feet of head and velocity.
- Darcy-Weisbach Pressure Loss Calculator
- Calculate pipe friction head loss and pressure drop with the Darcy-Weisbach equation and a Colebrook friction factor. Get psi, feet of head and flow regime.
