Enter Discharge Pipe total length in Metres. If your system has multiple pipe sizes, it is necessary to calculate each section of common size pipe and then add the friction loss for the next size pipe until all sections are included (only enter static suction & discharge head once). Where multiple branch lines and multiple discharge points exist, it is necessary to draw a system curve for each separate “system” then draw a new system curve by adding together all the flowrates which occur at the same head (ie: find the flow at 10 metres on each system curve and add flows together. Then repeat for 20 metres etc).
