How to calculate the diameter for import and export?
Head is determined by the conveying distance; it is necessary to know the vertical height, horizontal distance, number of bends, etc. The poster can provide the pump manufacturer with some detailed operating condition details, allowing professional staff to select the appropriate model.
The diameter of the inlet and outlet pipes is determined based on the flow velocity~~~ Then, reducers are used to connect them to the pump； Head calculation is obtained by adding the frictional loss along the pipeline, the outlet back pressure, and the lift head, and then multiplying the result by a coefficient~~~~~~~~~~~
Head is calculated based on the height difference, pipeline bends, valve losses, etc
It can be estimated; it depends on the application. Generally, the inlet diameter is larger than the outlet diameter. The diameter can be found using a table that provides values for flow velocity based on different diameters. The head loss is usually calculated by adding the maximum transmission distance to the vertical height difference. For elbows, a pipe loss of 0.5 meters is assumed; for gate valves, it’s 1 meter. For other types of head losses, an additional 3 to 5 meters can be added.
