Souders-Brown Equation Calculator

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

The Souders–Brown equation for obtaining the maximum allowable vapor velocity in vapor–liquid separation vessels.

Souders Brown Equation formula

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

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

For example, when K = 0.2, PL = 35, PV = 10, then Apparent porosity is 0.316227766016838.
