Relationship between the head of a centrifugal pump and pipe length
Thread Content
What is the relationship between the head of a centrifugal pump and the length and height of the pipeline? An exact figure isn’t required; just a rough estimate will suffice. How should one make such an estimate?
Of course it matters; the head is calculated based on the characteristics of the pump’s outlet pipeline. The pipe length and height are calculated using Bernoulli’s equation; it’s very simple. It can also be estimated simply: 1 meter of vertical height counts as 1 meter, and 10 meters of length also counts as 1 meter, allowing for an approximate calculation of the total head. It is still recommended to carefully calculate using Bernoulli’s equation.
I agree with the view above: for horizontal distances, a value of 8 meters is used as 1 meter of head; in the case of valves, elbows, etc., 3 of them are counted as 1 meter of head.
