hi all, I'm going to be building a screen printing table and ran into a question of airflow. Not being much of a science minded person I came across this site and thought I might find some help. Basically think of a box (4x25x35 roughly) it's airtight. except for a bunch of 1/16" holes drilled through the top. The holes are to hold down the paper. Now I need something to propel the air out of the box so that it sucks in through the holes, sucking down the paper. I had thought computer fans would be nice as they would fit nicely and they are light and can be transported easily. my question is how much cfm would the fans have to be able to push to pull the paper flat (the paper is relatively thick BTW). Is there a formula of somekind that could help me here, or does anyone know roughly through experience what it would take? I looked around and most fans seem to move between 35-119 that are the right size. Another question is if this could be done with say two or three, et cetera, would it push as much air if the fan were lined side by side as if they were sandwiched together producing a tunnel of sorts. It almost seems logical to me that a tunnel might move more air, any insight is appreciated.
