Centrifugal pumps are widely used in various industries for the transportation of fluids, especially water. Understanding the specific speed of a centrifugal pump is crucial for its efficient operation. In this article, we will delve into the concept of specific speed and its significance in the performance of a centrifugal pump delivering 750 litres of water per second against a specified head.
The specific speed of a centrifugal pump, delivering 750 litres of water per second against a
Mechanical Engineering
In the realm of mechanical engineering, centrifugal pumps play a vital role in fluid transportation systems. The specific speed of a centrifugal pump is a dimensionless number that characterizes the pump's operating conditions and performance. It is defined as the speed at which a geometrically similar pump would run if it were of unit size and delivering one unit of flow rate against one unit of head.
Mechanical Engineering
The specific speed of a centrifugal pump is calculated using the formula:
\[
N_{s} = \frac{N \sqrt{Q}}{H^{\frac{3}{4}}}
\]
Where:
- \(N_{s}\) = Specific speed of the pump
- \(N\) = Rotational speed of the pump (in revolutions per minute)
- \(Q\) = Flow rate of the pump (in cubic meters per second)
- \(H\) = Total head developed by the pump (in meters)
Mechanical Engineering
For a centrifugal pump delivering 750 litres of water per second against a specified head, the specific speed can be calculated based on the given flow rate and head. By plugging in the values of flow rate (750 litres per second), rotational speed, and total head into the specific speed formula, the specific speed of the pump can be determined.

Timed double flow twin-screw pumps: The most versatile of all types of screw pumps is the timed twin-screw pump. Although some manufacturers offer programs with standardized twin-screw pumps, they are often customized for a particular fluid, installation and service. They are designed for larger flow capacities than most other screw pumps and .Not enough water (or pressure) to pop up 8 spray heads when turning it on using the solenoid, but it works just fine when using the bleed screw. The zone is only using about 9 gpm, and there is 70 lbs of pressure just 15 .
