Liquids Flow Rate
Conventional Valve, Balanced-Bellows Valve, or Pilot-Operated Valve
The corresponding equations for liquid flow are the following:
Capacity correction factor, K,, due to viscosity.
Note that a preliminary orifice size must be determined in order to calculate Reynolds number. If the viscosity correction is significant, it may be necessary to iterate to get a final size.
