    Projectile Velocity from Pneumatic Test

    Wow!!! That was a bad mistake that I could see myself making. Long time ago as teenage lifeguards our manager(a slightly older teenager) made a CO2 powered screw gun using copper pipe, the CO2 tank from our Coke machine and just a regular phillips screw. Fun times...

    Projectile Velocity from Pneumatic Test

    rb1957, Yeah I have been trying to convince my higher ups that we should just be using the mass of the projectile. But I am also open to other methods and I realize my method would be worst case, just not sure how to get the actual case.

    Projectile Velocity from Pneumatic Test

    LittleInch, F=mA is actually what I was thinking if it were Hydrostatic testing. That would be much less violent than the pneumatic.

    Projectile Velocity from Pneumatic Test

    EdStainless, Yeah I had thought about an air rifle but that has the whole barrel to be building up speed with the pressure behind it. This would be nearly instantaneous.

    Projectile Velocity from Pneumatic Test

    Hi All, I am trying to design a pneumatic testing bay and want to make sure it will be robust enough. Need some help determining worst case velocity of a projectile in case of a failure. My projected worst case is if one of the fittings fails and comes shooting out.(the tank is overdesigned...
