Doing hydraulic calculations in a spreadsheet is an error-prone process. OpenFlows FlowMaster helps you perform hydraulic calculations for dozens of element types, from pipes and open channels to drop inlets and weirs: Solve for any unknown property Design for any desired characteristic Produce detailed reports and rating curves on the fly OpenFlows FlowMaster improves design productivity, ultimately saving 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 hydraulics 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 hydraulics 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.
