So dryness is not H2O content? All the gas suppliers I've looked at give H2O content for their gases, among other things, in ppm, and I just assumed that that was what "dryness" referred to. I'd still like to find a specific dryness standard for our purposes (refrigeration systems). Like I...
Our gas charging specification calls for "dry" nitrogen gas, but I don't know how "dry" the nitrogen needs to be. I know that different grades of nitrogen contain different amounts of water vapor; I was wondering if anyone could give me a specific dryness standard for nitrogen gas charging in...
Correction #2:
I checked the diabgroup document and I believe I've figured out what I did wrong; the equation on page 13 on the hexcel article needs another L in the numerator of both terms in order to account for the fact that P = q / b.
Correction:
When I use P = q / b (page 11) in the equation for deflection on page 13, all units cancel out, leaving me with a dimensionless answer for deflection, which is obviously not correct.
What am I doing wrong?
Thanks for your help, RPstress. I really appreciate it.
I think I'm going to base my calculation off of the first example problem from the hexcel article (page 12), modifying the deflection coefficients to make it a uniform load distribution, which is the case for me.
I am trying to calculate the maximum deflection of the wall of a walk-in air-handling unit. The wall is comprised of two steel sheets with foam insulation inbetween, and can be considered a rectangular beam, fixed at two ends, with a uniform load.
As I understand it, the equation for...
