How to calculate the pipeline pressure losses within the framework of water pumping?

Pressure loss calculation in water distribution

The selection of a well, drilling or surface pump is made depending on the water demand (flow) and the manometric delivery head.

The total manometric head (TMH) includes the pressure loss resulting from the water friction in the pipelines. This pressure loss is expressed in meters of water column.

In the table below, the pressure losses are provided in cm/m.

Example: Flow 2 m³/h, pipe diameter 1″ (26×34), pipe length 100 m.

>> Pressure loss (m) = 9 cm/m x 100 m = 9 m

If the pressure loss exceed 5 to 10 m or if is in the shaded part of the table, that means you need to choose different pipes with a larger diameter.

The upper values indicate the water speed in m/s – The lower values indicate the pressure losses in meters per 100 m of straight piping
