TDS 4 : How to add a water supply curve to an FHC project

For FHC to correctly calculate with a pump curve or water source, the curve must be flat (with constant pressure for the flow) or have a diminishing pressure as the flow increases. A second test to see if a pump curve is suitable for use in FHC is to see if, when plotted on a hydraulic graph paper (pressure scale is to the power of 1.85 (NFPA) or squared law), it produced a nearly straight line. FHC cannot calculate with a pump curve, which is parabolic. We recommend contacting the pump manufacturer for advice if you have such a pump.  

 

Detailed information on how to use a pump curve is given in our TDS 4 - How to add a water supply curve to a FHC project and you recommend that you download and follow the advice in that document.
