Souders-Brown Equation Calculator: Max Vapor Velocity for Efficient Separator Design

Calculate Maximum Allowable Vapor Velocity

This K-factor unit will determine the output velocity unit.
Ensure liquid and vapor densities are in the same unit.
Ensure liquid and vapor densities are in the same unit.

Utilize the Souders-Brown Equation Calculator to determine the maximum allowable vapor velocity in process equipment like flash drums, distillation columns, or knockout drums. Optimize your designs to prevent liquid entrainment and ensure efficient phase separation. Essential for chemical and process engineers seeking reliable calculations.

Formula:

Vmax = K × √((ρL - ρV) / ρV)

  • Vmax: Maximum allowable vapor velocity (e.g., ft/s or m/s)
  • K: Souders-Brown Coefficient (or K-factor), dimensionless or with units compatible with Vmax (e.g., ft/s or m/s). This factor depends on system geometry and operating conditions.
  • ρL: Density of the liquid phase (e.g., lb/ft3 or kg/m3)
  • ρV: Density of the vapor phase (e.g., lb/ft3 or kg/m3)
