  • Maximum Velocity for Water in Hydraulic Calcs?

    Maximum Velocity for Water in Hydraulic Calcs?

    If you have huge friction losses, you will need a higher pressure from your water supply and it is never advisable. The art is to find the equilibrium between the efficiency (limited friction loss = larger pipe) and the cost (larger pipe = larger cost and possible obstruction issues) But if your water supply is able to compensate your high friction loss in a small portion of pipePuhui Pipe manufacturer in China no big deal.
