    gas expansion calculation

    If we are talking ideal gas, isenotropic flow, with M=1 then clearly it is choked flow. Stagnation temp would be 300 K. In this case, downstream static pressure is 6, 8, or 10 mTorr.

    gas expansion calculation

    I am flowing 100 sccm gas through 10 orifii of diameter 0.016". The gas is either B2H6 or BF3. I want to do a gas expansion calc to determine a minimum pressure gradient needed to establish a sonic front.
