The discussion focuses on determining the expansion rate of nitrogen gas at various psi levels at room temperature, specifically for optimizing the velocity of piston arms. Participants emphasize the relationship between the speed of the piston and the force exerted, suggesting that higher velocities can enhance the propulsion of objects. There is also a consideration of alternative methods, such as heating nitrogen to increase performance. Overall, the conversation highlights the importance of understanding gas dynamics in pneumatic systems.

jooster said: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
Drakkith said: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.
jooster said:the faster the ram moves the higher the velocity can be reached to propel an object
