"WebUse Hazen-Williams formula for head losses in discharge pipe and add up minor losses. Don't calculate it for a single flowrate. Set up the spreadsheet to calculate from a flowrate of 0 to a flowrate that is larger (nearly double) than the desired pump flow rate. That is your TDH curve for your pump to overcome, TDH on y-axis and flowrate on x-axis. " - Hazen-williams calculation
