Pipe Hydraulics Calculator
Calculate flow velocity, friction loss, and determine optimal pipe sizes for your irrigation system design.
Pipe Hydraulics Calculator
Interactively calculate water velocity and friction loss for your selected pipe.
Calculated Results
Water Velocity
3.00 ft/s
SAFE (ideal is < 5 ft/s)
Pressure Loss
0.02 psi
Over 100 ft of pipe
Why This Matters
Choosing the right pipe size is critical. If velocity is too high, you risk water hammer (damaging pressure surges). Too much friction loss means the sprinklers at the end of the line won't have enough pressure to operate correctly, leading to dry spots.
