chromatography problems!

hi guys!

i am doing the chromatography. in scaling up i have to increase my volumetric flow rate but maintain my linear flow rate. my problem is i don't know how to calculate the column cross sectional area (cm2). i hope you guys who work with this area can tell me how i can calculate it when the radius of the column is 3cm and the height is 15cm.


Linear flow rate (cm/hr) = volumetric flow rate (cm3/hr) /
column cross-sectional area (cm2)



thanks a bunch!

Cross section of a column should just be area of a circle. pi*r^2
...unless I'm misunderstanding something about your question.

thanks Moonbear! i think you are right!
