Flow Calc is a computer software program designed to calculate common Open Channel Flow hydraulic characteristics using only the methods of the Manning's Equation for regular and irregular channel geometries for steady uniform flow including circular and elliptical pipes.
Flow Calc provides an easy to use interface that is streamlined and simplified for both English and SI Units. Extensive efforts were undertaken to provide a single screen interface to provide the most functionality for the design engineer. Effectively this allows the design engineer to monitor and correct channel geometries on the fly while at the same time being able to view the computational results immediately. Along with the data input controls for manual data entry, spin-controls are additionally provided to facilitate design review dynamically. A graphical representation of the channel geometry as entered by the design engineer provides a visual aide of the water surface elevation that is continually adjusted based upon input values.
Copy and Paste
Computational results can be printed or copied to the clipboard - Including the Graph Output at a scale specified by the design engineer.
In addition to entering irregular channel sections, Flow Calc provides the design engineer with templates for common channel geometries, which may be further modified as may be desired by the design engineer. Templates included are rectangular channels, V-Shaped Channels, Trapezoidal Channels, and common street sections for 60 ft, 80 ft, and 100 ft right-of-ways. For pipe flow analysis, common templates for circular and elliptical pipe are included.
Flow Calc provides an extensive Mannings N table as obtained from the Handbook of Hydraulics, Seventh Edition, Table 7.14, by Ernest F. Brater, Horace W. King, James E. Lindell, and C.Y. Wei. Along with this comprehensive Manning's N Table of roughness coefficients, Flow Calc allows the design engineer to select any of the 6 commonly accepted methods for computing a weighted roughness coefficient across a channel section as follows:
Flow Calc provides the design engineer with a Discharge versus Depth rating table. The results of produced by this table may be either copied for use within another application to create custom reports or may be printed directly to a printer.
Flow Calc Professional Reports
Flow Calc provides the design engineer with professional reports. Computational results can be printed or copied to the clipboard - Including the Graph Output at a scale specified by the design engineer.
