centrifugal pump head rise calculation|centrifugal pump selection calculator : distributor Jan 8, 2024 · Calculate the head of a centrifugal pump pumping water at 20°C with a flow rate of 10L/s. The vacuum gauge at the inlet reads 0.031Mpa, and the pressure gauge at the outlet reads 0.126Mpa (gauge pressure). Atlantic Worm Pump AWP 10000 is a high volume screw pump delivering an output of 10 m3/hr and is driven by a 10 HP (7.5 kW) electric motor. With a special Rotor Stator at its heart, the machine is ideal for pumping liquid screed, grout and mortar with grain size up to 10 mm.

In multiple screw pumps, each wrap of screw thread effectively forms a stage of pressure capability. High pressure pumps have 5 to 12 stages or wraps, whereas low pressure pumps may have only 2 or 3 wraps. The presure capability of a two screw pump, for example, is illustrated in Figure 1. 90 degrees from the plane of the shafts.
Centrifugal pumps are widely used in various industries to transport fluids by converting mechanical energy into hydraulic energy. One crucial aspect of pump performance is the calculation of head rise, which determines the pump's ability to overcome resistance and lift the fluid to the desired height. In this article, we will delve into the intricacies of centrifugal pump head rise calculation, exploring the formulas, diagrams, and online tools used in this process.
This page is explaining how to calculate the head rise of a fluid when going through a pump. The head rise through a pump is the difference of head (or energy) that a fluid experience in between the inlet and outlet conditions of a
Centrifugal Pump Head Calculation Formula
The head rise of a centrifugal pump can be calculated using the following formula:
\[ H = \frac{P_{outlet} - P_{inlet}}{\rho \cdot g} + \frac{V_{outlet}^2 - V_{inlet}^2}{2 \cdot g} + Z_{outlet} - Z_{inlet} \]
Where:
- \( H \) = Total head rise (m)
- \( P_{outlet} \) = Pressure at the outlet (Pa)
- \( P_{inlet} \) = Pressure at the inlet (Pa)
- \( \rho \) = Density of the fluid (kg/m³)
- \( g \) = Acceleration due to gravity (m/s²)
- \( V_{outlet} \) = Velocity at the outlet (m/s)
- \( V_{inlet} \) = Velocity at the inlet (m/s)
- \( Z_{outlet} \) = Elevation at the outlet (m)
- \( Z_{inlet} \) = Elevation at the inlet (m)
