    Velocity limitation in water pipes Pipelines, Piping PE100

    20/6/2012· My hydraulic analysis indie that due to high available static heads, the water velocity in a relatively short ~50 m 8" pipe occasionally reaches velocities as high as 15 20 m/s. My understanding is that such high velocities could lead to excessive noise, high erosion rates, and even large piping loads; therefore, have to be limited but I do not know to what value.
