Sizing Pump

Well diameter should be determined as per the pump size, it should not be the other way around

To size a well pump there are two main things which needs to be considered i.e. your required flow rate and your required amount of lift

Flow rate: it is the volume of fluid travelled in unit time (usually measured in LPM or GPM or m3/h) Lift: amount of lift can also be determined as total dynamic head (usually measured in mtr. Or ft.)

Determine TDH (Total Dynamic Head)

TDH = Pumping level + Vertical Lift + Friction loss (pipe and fittings)

Determine Friction losses

Friction losses = Total length of pipe*Friction loss factor + Friction loss of fittings
