Solve-for-anything hydraulic toolbox
Solve for any unknown property, design for any desired characteristic, and produce detailed reports and rating curves on the fly.
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.
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.
- Design and analyze dozens of element types, such as pressure pipes, open channels, weirs, orifices, and inlets
- Replace the error-prone spreadsheet process for reliable calculations on a wide variety of hydraulic elements
