Easy and intuitive
This app gives me just the right amount of flexibility to enter system parameters to see if the set up will work, before I bring the pump, hoses and fittings to the job site. It also lets me get a rough estimate of cost by making pump selection easier. There is a good selection of hose types to choose from. It even lets me enter two different hose types. Overall, this is a handy tool for calculating both TDH and NPSHa.
