WebJul 5, 2024 · fall of piper from the reservoir to discharge: 14m. Pipe material: cement lined iron ductile. I've calculated the flow rate due to gravity alone using hazen-williams but this doesn't take into account the head of water and so the discharge flow is far lower than the reality. I'm unsure of how to incorporate pressure into the calculations. WebFig. 3.55 illustrates this by plotting the pump discharge head vs. flow for high- and low-suction tank conditions. The control valve, however, tries to maintain a steady pressure. As a result, the flow rate varies as the suction pressure varies. In some cases, the flow rate may drop to below the recommended minimum at very low head conditions. bjm conference 2023
