Centrifugal Pump Head Calculation Formula
The calculation of head for a centrifugal pump involves several key parameters, including the pump's flow rate, specific gravity of the fluid, efficiency of the pump, and the impeller diameter. The formula for calculating the total head (H) generated by a centrifugal pump is as follows:
\[ H = \frac{Q \times SG}{3960 \times \eta} + \left( \frac{V^2}{2g} \right) + H_s \]
Where:
- \( H \) = Total head (in meters)
- \( Q \) = Flow rate (in cubic meters per second)
- \( SG \) = Specific gravity of the fluid
- \( \eta \) = Pump efficiency (in decimal)
- \( V \) = Velocity of the fluid at the impeller outlet (in meters per second)
- \( g \) = Acceleration due to gravity (9.81 m/s\(^2\))
- \( H_s \) = Static suction head (in meters)
