Friction Loss Calculator
for Sanitary Process Piping
Estimate pressure drop in 3-A and ASME BPE sanitary tube systems. Accounts for pipe friction, fittings, elevation change, and additional system losses.
Estimate system pressure drop in seconds
When sizing a pump for a sanitary process line, you need to know the total head your system demands — friction from the pipe run, losses through fittings and valves, and the pressure required to lift fluid to a higher elevation. This calculator handles all of it in one place, using 3-A standard tube dimensions and the Darcy-Weisbach equation.
Enter your tube size, flow rate, pipe length, fittings count, and vertical rise. The calculator returns individual loss components and a total system head — in PSI or kPa.

Darcy-Weisbach · 3-A tube dimensions · Colebrook friction factor
Positive = pumping uphill · Negative = downhill (reduces required head)
Use for heat exchangers, strainers, vessels, nozzles, or other known pressure drops not listed above.
