The flow rates of … WebRather, a doubling of flow rate will result in a quadrupling of differential pressure. Likewise, a tripling of flow rate results in nine times as much differential pressure developed by the fluid-accelerating flow element. …

WebJun 8, 2024 · So, when pressure in the pump causes more load on the motor, it slows down. When the motor slows down, the flow rate drops at the same percentage. A motor that operates at about 2000 RPM at low pressures will typically slow down to about 1750 RPM when the pump is pressurized to the maximum rating. It stands to reason, then, … WebApr 6, 2024 · We expect the pressure drop to be 1 over (⅔)^4.9 or about 7 times higher than the original pipe. At 0.3 gpm, the pressure drop is 3 inches.
