Next, measure this flow rate at 80%, 60%, 40%, and 20%, as well as the upstream and downstream pressure. The sonic conductance C can be calculated based on this maximum flow rate. Substitute the data of the others into the subsonic flow formula to find b, and calculate the critical pressure ratio b from that average.
