Viscosity and density of diesel exhaust at 550-600F may be hard to find. Try soliciting one of the manufacturers like Cummins or Detriot Allison.

Re: oxygen @ 50 psi flow rate
I have never come accross the compressible flow formula and mine actually used the wrong differential by 14.7 PSI (discharging from gage pressure to atmosphere...duh!)! Placing the correct value in my version yields about 283 SCFM. I'm going to work through the other using pipe k=0.04 and x=1.4. I'l...

Re: purpose
Yeah, I just helped oxygendoc with a theoretical flow problem. Darcy Weisbach would have been perfect but in its absence....

Re: oxygen @ 50 psi flow rate
The maximum theoretical exit velocity can be calculated by writing the energy equation using a pressure differential (delta p) of 64.7 PSIA (assume constant source), zero frictional head losses in the pipe and zero elevation change. Manipulate the equation to solve for v2 and assume v1 = 0. The actu...

I like the flow calculations available on the site but what is the purpose of this blog?
