Question

Empirical equation that is applicable for flow through beds at \( Re = 1.0 \) is

• A. Haigen-Poiseuille equation
• B. Burke-Plummer equation
• C. Ergun equation
• D. Kozeny-Carman equation

Hint:

Use Kozeny-Carman model when flow is slow and bed is densely packed.

Answer 1

The Correct Option is D

Kozeny-Carman equation applies to laminar flow through packed beds (low Reynolds number):
\[ \Delta P \propto \frac{\mu \cdot v \cdot (1 - \epsilon)^2}{\epsilon^3 \cdot d_p^2} \]
