New Online Hydraulic Calculators for PVC Pipe

Posted By John Houle on Apr 8, 2025

Uni-Bell has just published two online hydraulics calculators. A pressure-pipe calculator determines friction loss for PVC and PVCO pressure pipes and a nonpressure-pipe calculator determines slope, flow volume, and flow velocity for PVC sewer pipes.

No more searching through pages of tables looking for the right info — now you simply enter pertinent data into the calculator and out comes your answer.
