Pipe pressure drop calculator – single phase

This is a sample of the Pipe pressure drop calculator. To access the working calculator, please sign up for free membership trial.

W - Mass flow capacity kg/h
ρ - Density of fluid kg/m3
µ - Viscosity of fluid (either liquid or gas) cP
e - Effective roughness of the pipe mm
d - Nominal diameter of the pipe inches
sch - pipe schedule
Fluid Velocity m/s
Volumetric flow m3/hr
Reynold's No.
Pressure loss bar/km

This calculator gives value of pressure drop per unit length of a straight line. But usually pipes are accompanied by bends, fittings, valves etc. Use EnggCyclopedia's K-factor calculator to obtain pressure drop across fittings in a line.

For a two phase flow case through a pipe, use EnggCyclopedia's two phase pressure drop calculator.
