Vol Flow rate of gas inside corrugated pipe 1

[dgau008]

hi,
how we can find vol flow rate of gas inside corrugated tube???

thanks

Probably by testing. Nobody usually wants to flow gas inefficiently through a CMP, so not any method, or even data, out there that I know of. Maybe they do that in mining work.. maybe.

It's old, like me, but "This bibliography is the result of an extensive literature survey in an attempt to obtain detailed information, both empirical and theoretical, on the pressure drop occurring in corrugated hoses, bellows, and gimbal joints":

Good luck,

Good work Latexman.
I should have known NASA would have attemped to do it.

thanks guys, so with what method we can get flow rate of gas in corrugated pipe

Maybe Latexman knows. I can't read that small print.

same here BigInch

I did better than I expected. The old document used the Fanning friction factor. The one at the url below has been converted to the Darcy-Weisbach friction factor. My company and I have used this correlation for years and years.

Good luck,

Note also that the flow through corrugated hose can induce vibrations that can damage the hose.
