Information

Straight Pipe

Laminar flow

Calculation of pressure loss in a straight pipe for laminar flow regime of single-phase fluid flow only. See more information.

Turbulent flow

Calculation of pressure loss in a straight pipe for turbulent flow regime of single-phase fluid flow only considering surface roughness. See more information.

Overall flow

Calculation of pressure loss in a straight pipe for laminar or turbulent flow regime of single-phase fluid flow only considering surface roughness. See more information.

Two phase overall flow

Calculation of pressure loss for two phase flow in a horizontal or vertical straight pipe for an overall flow regime considering frictional, momentum and geodetic pressure loss. See more information.
