# Kozeny Carman Equation Calculator

Posted by Dinesh onThe Kozeny Carman equation (or Carman Kozeny equation) is a equation used in fluid dynamics to calculate pressure drop, clean bed head loss of solids.

### Formula:

( ?p ⁄ L ) = (180?⁄ ?_{s}^{2} × D_{p}^{2}) × [(1 - ?)^{2} / ?^{3}] × ?_{s}

? - is the viscosity of the fluid;

?

_{s}- is the sphericity of the particles in the packed bed;

D

_{p}- is the diameter of the related spherical particle;

? - is the porosity of the bed;

?

_{s}- is the superficial or empty-tower velocity;

?p - is the pressure drop;

L - is the total height of the bed;
