How to choose the pump head
Thread Content
Given the external conditions (piping diameter, pipeline length, system pressure, height difference for liquid transfer, etc.), how is the head of the pump to be selected calculated? That is, what is the formulaic relationship between them?
H head is greater than or equal to H pipe resistance + H level difference – H pressure before the pump + H pressure in the receiving tank

Shh, stop calling each other comrade upstairs

Just to add, some extra margin needs to be left; the current pumps have poor sealing properties
First, calculate the pressure required by the device, and then select the pump (with a margin of about 3 meters); for details, see Principles of Chemical Engineering
Hydraulics is used to calculate the hydrostatic level and pipe friction loss, in order to determine the required pressure difference
