I came across one equation called chen's correlation for pressure drop in packed bed. I could not understand what unit of measurements to be used because the equations seems to be semi emperical. Can any one help ?

Dear Cyberspider789,

 

Maybe Chen equation is only a part of your procedure. The Chen equation is for Fanning friction factor determination.

Where:

f = Fanning friction factor

k = absolute roughness (in)

D = diameter (in)

k/D = relative roughness (unitless)

Re = Reynold’s number

 
¿Do you have another equation?, please send me for review.
 
Regards,
 
Napo.
