- By fitting an air vessel to the reciprocating pump, there is always a saving of work done and subsequently saving of power. The saving in case of a double acting reciprocating pump is
- By fitting an air vessel to the reciprocating pump, there is always a saving of work done and subsequently saving of power. This saving in case of a single acting reciprocating pump is
- For very high discharge at low pressure such as for flood control and irrigation applications, following type of pump is preferred
- For small discharge at high pressure, following pump is preferred
- Manometric head, in case of a centrifugal pump, is equal to
- Multistage centrifugal pumps are used to
- Reciprocating pumps are no more to be seen in industrial applications (in comparison to centrifugal pumps) because of
- General energy equation holds for
