use the formula n = p + h – f, where n is the desired nozzle pressure in psi, p is the engine (pump) pressure in psi, h is the head gain or loss in psi, and f is the friction loss in psi.  For h, use a positive value of 0.5psi/foot if the head is adding pressure to the hose (nozzle downhill from pump) or a negative 0.5psi/foot if the head is subtracting pressure from the hose (nozzle uphill from pump). For f, use 5psi for the friction loss generated by each fitting in the line. A progressive, 6 length hose lay has five fittings connecting the hoses together.  The nozzle outlet is feet below the engine.  If the desired nozzle pressure is , at what pressure does the engine need to perform?
