Another tag is a good idea, but hydraulics is far more appropriate than fluid-dynamics.

The question is related hydraulic fluid the fluid-dynamics might be a good tag

| Mar 6, 2015 at 12:03 | comment | added | Blue7 | @ratchetfreak. Okay this is starting to make sense now. The load piston end only needs to move a small amount to be able to close the packing unit. From my calculations the force on the piston will be around 3 Mega Newtons. This sounds ridiculous to me, but it is feasible because the load piston isn't moving much (hence smaller work done) but the compressor piston is moving more? | |
| Mar 6, 2015 at 11:48 | comment | added | ratchet freak | The key is that the distance traveled by the compressor piston is larger than the distance traveled by the load piston end (remember that work is distance*force) | |
| Mar 6, 2015 at 11:43 | comment | added | Blue7 | @ratchetfreak so the compressor uses a smaller area to generate the needed pressure, and the piston uses a larger area to increase the force? I somehow feel like conservation of energy isn't being held. if the area of the pisiton is 0.3m^2, and the pressure is 1500 PSI, this gives a force around 3MN. I find it hard to believe that this pump can provide 3MN. Can you please explain? | |
| Mar 6, 2015 at 11:19 | comment | added | ratchet freak | pressure over large area can easily give huge forces, The hydraulic compressor will use a much smaller area to generate the needed pressure with smaller needed force | |
