Calculating Force and Energy in Pneumatic Air Testing

[skaboy607]

Hi,

Is it possible to determine the force (energy) behind a 300dia blank when under a pressure of 0.5bar and subsequently how far the force (energy) may move the blank which has a mass of 16kg?

I know the volume and pressure of the air so can the stored internal energy be approximated by (3/2)PV?

Thanks

Yes.

Directly, you can conduct the experiment.
Mathematically you can construct a model and hope that it gets close enough to be useful.
Multiplying the pressure by the area, for instance, gets you the force at that pressure.
You have rhe correct approximation for internal energy... careful: not all that energy will go into, say, moving thr blank.
