The cast materials used in centrifugal pumps vary depending on the desired material composition and the mechanical and technological properties required. See Fig 1 . Thermoplastics have a particularly important role to play as design materials for impellers and diffusers whereas elastomers are used for sealing elements or as coating materials.

Centrifugal pumps mounted on the outside of the tank do not require this but have some sort of inlet that is located in the fuel. This can be a tube in which a shutoff valve is located so the pump can be changed without draining the tank. The inlet of both types of centrifugal pump is covered with a screen to prevent the ingestion of foreign .
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.

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.
