Thanks cjl & boneh3ad. I thought the restriction was choked, but experimental results suggest otherwise. The geometry is as follows: The restriction is created by an annulus made up by a tapered shaft in a plain hole. The hole is 1.58mm in diameter. The plate thickness is 0.85mm. The shaft...

I am considering the effects on volumetric and mass flow rate for two conditions: Condition 1) 1013mBar, 21C (Air density as per) Condition 2) 700mBar (10,000ft) 21C (Air density as per) Setup: A variable flow restrictor is connected to a constant source of oxygen at 50 psig. The variable...
