We have a vacuum manifold that sucks a piece of paper to a wheel. There are 7 holes with an approximate diameter of 1/8" for each.
I would like to verify that the hose diameter is appropriately sized to ensure that the hose or its connectors are not the choke point, but the 7 holes in the manifold are.
I don’t believe I can get a good and accurate rating of the vacuum, as this is in a commercial application and it is on a communal vacuum line. My hope would be that at different flow rates, the holes would at least retain the same suction of the supply hose.
My intuitive assumption would be that I would need to match the cross sectional area of the holes to the cross sectional area of the hose (or its connectors, depending on which one is the smallest.
It has been years since I had fluids in school, and I don’t have my book available, so any help in figuring out just what needs to be calculated. I am not even sure what the most important variable is in this case, pressure, air velocity, or the flow rate.
These holes need to perform two functions. The first is to attract the paper, and the second is to retain its position once sucked down to the manifold.
Thank you in advance, your help is greatly appreciated.
