# Nitrogen expansion rate?

 P: 2 i'm trying to figure out the expansion rate of nitrogen at any given psi in room temperature. roughly in fps. trying to calculate how fast we can move a piston arm to get maximum velocities

Im not sure on this, but may i ask why the velocity is so important? If you are looking at doing work with this piston it might be easier to simply move it at a slower rate, but with more force. (Heating the nitrogen to a higher temp, using more of it, ETC)

If that makes sense.

the faster the ram moves the higher the velocity can be reached to propel an object
