Souders-Brown Equation Calculator

The Souders-Brown equation has been the tool for obtaining the maximum allowable vapor velocity in vapor-liquid separation vessels (variously called flash drums, knockout drums, knockout pots, compressor suction drums and compressor inlet drums)

Liquid Density (PL):
Vapour density (PV):
Vapour Velocity Factor (K):
Apparent porosity:

 
   
  



Souders Brown Equation:

V = ( K * sqrt((PL - PV) / PV) )

Where,
V = Maximum Allowable Vapor Velocity
K =Vapor Velocity Factor
PL =Liquid Density
PV = Vapor Density
