Pump head and head loss
Thread Content
Centrifugal water pump: flow rate of 200 m3/h, head: 50 M. The main pipe is galvanized steel with a diameter of DN150; the inlet pipe is 100 M long, and the return pipe is also 100 M long, with a vertical rise of 4 M. Given that the inlet pressure needs to be maintained, should the head loss associated with the return pipe be taken into account?
Where does the 100-meter water intake pipe draw water from? Is it from an above-ground tank, an underground tank, or something else?
Give a simple diagram, and I can answer your question
