Description

Given the values of flow, manometric head, and pump rotation, this calculation estimates the required NPSH (Net Positive Suction Head). In general, the obtained value is very conservative, ensuring the pump's safe operation.

Input and output parameters table:

Parameter	Standard Units	Description
Flow ($Q$)	L/s	Pump flow rate
Manometric height ($H$)	m	Pump's manometric head
Pump's rotation ($w$)	rpm	Pump's rotational speed
Required NPSH	m	Estimated required NPSH
