Hi,

I'm having some trouble with finding the "choke" point of a 1.5" diameter pipe.

Conditions:

300 kPa

383 deg K

1.5 in D

I've tried using this little guy, http://www.grc.nasa.gov/WWW/K-12/airplane/mflchk.html, with the Mach = 1, and only get ~1.5lb/min, which can't be correct. Can't figure out what I'm missing?

Thanks

Nate
