Souders–Brown Calculator

Calculate the maximum vapor velocity using: $v_{f} = K \sqrt{\frac{ρ_{L} - ρ_{V}}{ρ_{V}}}$

* Enter the Souders–Brown constant $K$ (m/s), liquid density $ρ_{L}$ (kg/m³), and vapor density $ρ_{V}$ (kg/m³).

Step 1: Enter Parameters

Souders–Brown Constant,

K

(m/s):

Typical values: 0.1 – 0.3 m/s

Liquid Density,

ρ_{L}

(kg/m³):

e.g., 1000 kg/m³ for water

Vapor Density,

ρ_{V}

(kg/m³):

e.g., 5 kg/m³ for a typical hydrocarbon vapor
