We attempted to model the pressure loss of the water from the pump to the end of the nozzles. We learned about many different modeling strategies, but the one we used was the Equivalent Length Method. This method allows us to describe pressure drop through a PVC component as the pressure drop through a length of a pipe. As an example, the pressure loss through a 1” PVC Tee connector is equivalent to pressure loss through a 0.6” length of pipe. Or pressure loss through a 1” 90 degree elbow is equivalent to the pressure loss through a 2.5” pipe. These numbers were taken from EngineeringToolBox.com. The website suggests that these values are not accurate, though they provide an insight on the estimated pressure loss of a system. Once we calculated the initial pressure from the submersible pump, we plug in our values in to the equation for pressure loss in pipe:
