And to add further....

There may also be a derating of force based upon the angle that the force is applied by the piston. For a good overall explanation, go to http://pneumaticsfirst.org and down load the powerpoint presentation dealing with pneumatics.

Do not forgot the time dimension part of the power equation. Cylinders also have a force versus time curve for each given pressure . My team has done some experiments and have proven that these curves are not linear. I have attached a sample of our experimental results. It is difficult to characterize pneumatics because the entire system affects the available airflow volumes (think of a current limiting analogy from electronics), so these curves are very dependent on your set up. I'm too busy right now to go into any more details but I may do a white paper on the power curves of our pneumatic systems during the off-season.

Don't forget to do a "Save As" on the XL file.
