Pressure Drop Through Packed Bed Calculator

This tool calculates the pressure drop in fluid flowing through a packed bed using Carman-Kozeny equation assuming a laminar flow.



Type the required values to get the pressure drop:

Packing length (L, m)


Sphere equivalent particle diameter of Packing (d, m)


Bed porosity (ε)


Fluid viscosity (µ, kg/ms)


Superficial velocity (U, m/s) [cross-sectional average fluid velocity]




Pressure drop (Pa)
