soconfused Posted September 23, 2004 Share Posted September 23, 2004 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 have asked the people in the math forum, but it seems like we get nowhere, so i hope you guys who work with this area can tell me how i can calculate it when the radius of the column is 2cm and the height is 5cm. Linear flow rate (cm/hr) = volumetric flow rate (cm3/hr) / column cross-sectional area (cm2) thanks a bunch! Link to comment Share on other sites More sharing options...
Skye Posted September 24, 2004 Share Posted September 24, 2004 pi x r^2? Link to comment Share on other sites More sharing options...
soconfused Posted September 24, 2004 Author Share Posted September 24, 2004 hi skye! are you sure column cross-sectional area (cm2) has this formula? thanks! Link to comment Share on other sites More sharing options...
Skye Posted September 24, 2004 Share Posted September 24, 2004 Yep, the other thread seems to have better information. Even pictures. Link to comment Share on other sites More sharing options...
veera Posted August 6, 2005 Share Posted August 6, 2005 i think this is very primitive question. volumetric flow rate= cs area*velocity where c.s arae = pi/4*dia^2 i hope it will help you. Link to comment Share on other sites More sharing options...
