centrifugal pump shaft power calculation|submersible water pump size chart : custom The calculator below can used to calculate the hydraulic and shaft power of a pump using Imperial units: q - flow capacity (gpm) γ - specific weight of fluid (lb/ft 3 ) The screw pump is the oldest positive displacement pump. The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation. A later screw pump design from Egypt .

Eventually, motors were employed to power screw pumps. Who invented the Archimedes screw? There’s evidence that the Archimedes screw was in use during the Hellenistic period of ancient Egyptian history, in around the 3rd century BC. At that time, the Archimedes screw was used to raise water from the Nile, functioning as an irrigation tool .
Centrifugal pumps play a crucial role in various industries, including oil and gas, water treatment, and manufacturing. These pumps are used to move fluids through a system by converting mechanical energy into hydraulic energy. One important aspect of centrifugal pump operation is calculating the shaft power required to drive the pump efficiently.

How to Calculate the Pump Hydraulic Power?
The hydraulic power of a centrifugal pump can be calculated using the pump's flow rate, pump head, and the density of the fluid being pumped. The formula to calculate the pump hydraulic power is as follows:
\[ P_{\text{hydraulic}} = \rho \times g \times Q \times H \times \eta \]
Where:
- \( P_{\text{hydraulic}} \) = Hydraulic power (W)
- \( \rho \) = Density of the fluid being pumped (kg/m³)
- \( g \) = Acceleration due to gravity (9.81 m/s²)
- \( Q \) = Flow rate of the pump (m³/s)
- \( H \) = Pump head (m)
- \( \eta \) = Pump efficiency
