Describe the methodology for obtaining the pump curve in a project, where data are collected at five points with different pressures in the pump (10 psi, 15 psi, 20 psi, 25 psi and 30 psi), where to find these Q flow rates a 1000 ml bottle is used and the time needed to fill it is timed, for each of the pump's five pressure points. The gauge pressure H in meters of water column achieved should also be observed, in order to construct the HxQ graph of the pump.
