stuck Posted July 13, 2009 Share Posted July 13, 2009 Hi all, Sorry if this is too off topic but I need some help. Does anybody know how to work out the pressure applied to a roller of known dimensions in PLI from the PSI applied to pneumatic cylinders attached at either end? Cheers in advance, Mick.

If you know the piston area of the cylinders in square inches (pi (3.141592654) x radius squared), multiply each by the PSI value of the air and add the two results (probably equal area cyclinders, so just double one). PLI is pounds per linear inch, so divide the result above by the length of the roller in inches. Done. Quote Link to comment Share on other sites More sharing options...
TheRecklessEngineer Posted July 13, 2009 Share Posted July 13, 2009 ^^^Wot errol said, just make sure you use the radius of your cylinder in inches (duh!) Whats wrong with metric anyway? Quote Link to comment Share on other sites More sharing options...

Bush65 Posted July 14, 2009 Share Posted July 14, 2009 Strictly speaking, as we live in a world with friction, this will reduce the cylinder force a little. But you may not need to worry friction, depending upon precision required. Quote Link to comment Share on other sites More sharing options...
