Re: Pneumatics holding their position

I keep reading about the 60 psi with a 2 inch bore, yada yada and people multiplying area by pressure to get force. I have yet to see someone account for the fact that in pressurizing the 2 inch bore cylinder, the overall pressure goes WAY down to less than 60 psi and i know my compressor can't recover that quickly. The tanks are small..... Am I doing something wrong, or does this make sense? That is, that you need to account for the overall pressure drop in figuring theoretical force exerted by piston.
