What is OpenFlows FlowMaster?

OpenFlows FlowMaster helps you perform hydraulic calculations for dozens of element types, from pipes and open channels to drop inlets and weirs. Improve design productivity and ultimately save project costs. OpenFlows FlowMaster’s interface is simple enough to be the easiest model you have ever used, yet so powerful, you will be solving real problems in just minutes.

Pressure pipe design

Perform a quick check or design by plugging in the known information and automatically solving for pipe length, start-and-stop elevations and pressures, discharge, diameter, and roughness.

Inlet and Gutter 

Design and analyze grate, curb, ditch, slotted, and combination inlets using calculations based on the FHWA Hydraulic Engineering Circular No. 12 and Circular No. 22 methodologies. 

Open Channel

Design and analyze channels, ditches, and free surface pipes of any shape including circular, box, elliptical, parabolic, and irregular channels.

Weir and orifice modeling

Size weirs considering discharge, weir coefficients, and crest, headwater, and tailwater elevations for the following types: rectangular, V-notch, Cipolletti, broad crested, or custom size.
