Ever use an air nozzle with compressed air? How about a pressure washer? Same physics either way
The smaller the hole, the higher the velocity...up to a point (density and mass come into play)...this is of course relative to the pressure behind the air (gas) to begin with.
Its actually the same whether its gas or fluid...a pin hole in a hydraulic line with enough pressure on it will spout a stream that will slice your arm off like a samurai sword...the same is true for high pressure gasses, but the range is shorter because the gas has less momentum (slows down in the atmosphere)
I know...I'm digging up old threads...but I'm reading to learn and thought what I posted here may be of some relevance.
I'm late the piston party...and playing catch up....and no, I'm not a physics professor...I'm a heavy haul truck driver, but my IQ is a bit higher than room temperature.
EDITED TO ADD: A smaller gas port would also lower the volume of gas that went through during the firing process...because of the fixed amount of time that the pressure was there....this turned into a deep subject, LOL. I suspect many of you already knew the smaller port lowered the volume...we've all read about over gassing...which is exactly what some are saying the piston system amounts to because of the smaller chamber....if it is smaller...I honestly don't know yet.
At least give me credit for trying to understand, LOL...and I will understand before its over...and its not about me saying one is better than the other...its like the man said earlier...I just want to understand them both, particularly the piston though because thats what I have.
Anybody ever compared gas port sizes on any of the new piston guns to a DI?
