Centrifugal pumps are specified every day based on their ability to deliver pressure and flow to a piping system. Often overlooked is the design of the pump suction piping. Unless carefully designed, a lack of pressure, or “head,” at the suction of a pump can lead to damaged equipment.
This course will introduce the concept of “head” as a measurement of fluid pressure. Using this concept, Net Positive Suction Head (NPSH) will be defined in terms of the piping system and the pump. The piping system will be analyzed to determine the NPSH available (NPSHA) and the capabilities of the pump will determine the NPSH required (NPSHR). To ensure the pump operates as intended, the NPSHA will need to be greater than the NPSHR for all operating conditions.
Many engineering disciplines are exposed to pumped fluid systems as a part of their professional responsibilities. The knowledge gained from this course will benefit those who are responsible for piping system design, operation, or maintenance, as well as those who are looking for practical knowledge about a fundamental engineering concept.
