Q: What is NPSH for a tank open to atmosphere? What would cause a negative pressure (vacuum) at the pump suction?
A: NPSH, or Net Positive Suction Head, is the amount of fluid energy at the pump suction in reference to absolute zero energy. In relation to centrifugal pumps, Net Positive Suction Head required (NPSHr) is the amount of fluid energy at the pump suction at which the pressure at the eye of the impeller drops below the vapor pressure of the liquid and vapor bubbles begin to form. Pump manufacturers test their pumps to determine the NPSHr over the range of operating flow rates for the pump.
The amount of fluid energy the piping system provides to the pump suction is called the Net Positive Suction Head available (NPSHa). NPSHa is a function of the following characteristics of the piping system on the suction side of the pump.
