Flow rate of the DN200 inlet main pipe pump
Thread Content
Seeking advice: The company’s main water inlet pipe has a diameter of DN200, is approximately 150 meters long, and a head of 30 is sufficient. I would like to know what flow rate the pump should have Is frequency conversion necessary? Thank you very much! ! ! !
The volumetric flow rate is approximately 340 m3/h
For water pressure flows below 0.3 MPa, the allowable flow velocity range is 0.5 to 2 m/s; your flow velocity is 340/3600/0.0314 = 3 m/s.
