Dear all,

 

I would like to ask you how I can calculate the width of downcomer for a single pass tray if I have data for the tray.

 

Also, I would appreciate your explanation why  if we see a tray from the top of the column it looks like the attached picture.

Or you can use the cylinder application at my website. I'm sure there are many more, too.

Thank you so much for the help of both! Mr. Bobby can you please tell me which is your website!

My main problem was to visualize why the tray looks like this from a top view. But, I will try to find a way to vizualize it. I am new engineer and sometimes I am struggling with the drawings, because I have never seen a distillation column only from books! haha

 

Thanks for your important help! :D
