Recommanded flow velocities for liquids

1.segment ball globe eccntric rotary plug: *Inlet velocity <= 10m/s continuous duty service, *Inlet velocity <=12m/s for infrequent duty

2.butterfly: *inlet velocity <=7m/s for continuous duty *inlet velocity <=8.5m/s for infrequent duty

3.Vsonic = 91.2 * SQRT(rT/M) r : specify heat T:temperature (K) M: moler mass
