Calculating Force and Energy in Pneumatic Air Testing

AI Thread Summary
To calculate the force exerted by a 300mm diameter blank under 0.5 bar pressure, the force can be determined by multiplying the pressure by the area. The stored internal energy can be approximated using the formula (3/2)PV, but not all of this energy will be converted into movement of the blank. The mass of the blank is 16kg, which will affect how far it can be moved by the force generated. Conducting an experiment can provide direct measurements, while mathematical modeling can offer useful approximations. Understanding these principles is essential for accurate pneumatic air testing.

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.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
