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

SINGLE PHASEFLOW INPUTS
W – Mass flow capacity kg/h
ρ – Density of fluid kg/m3
µ – Viscosity of fluid (either liquid or gas) cP
PIPE SPECIFICATIONS
e – Effective roughness of the pipe mm
d – Nominal diameter of the pipe inches
sch – pipe schedule
RESULTS
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.
