I’m really sorry to ask, but I have a question about head and flow rate
Thread Content
In two different piping systems, if pumps with the same head are used, will the water flow velocity be the same?
There is a manuscript in which one of the sentences reads, “Under the condition that the flow rate of the circulating cooling water remains constant (that is, the head generated by the forced circulation pump in circuit A is the same as that of the forced circulation pump in circuit B).” Here, A and B refer to two sets of circuits made of different materials, with different shapes and lengths. Is there anything wrong with that sentence?
When the pipe diameter is the same, the flow velocity depends only on the flow rate and not on the head. The resistance of a pipeline is related to its head; the greater the resistance, the higher head pump is required. This post was last edited by wang*neng on 2009-2-9 17:30.]
If the pump’s nameplate indicates a head of 100 meters and a flow rate of 100 cubic meters, and it feeds a pipe with DN100 over a distance of 100 meters, as well as a pipe with DN10 over a distance of 10,000 meters, I think the resistance difference will be significant enough to make the performance different.
