VQ7-6/7-8 How to Find the Flow Rate (at air temperature of 20C) Subsonic flow when P1 + 0.1013 < 1.89 (P2 + 0.1013) Q = 226S P(P2 + 0.1013) Sonic flow when P1 + 0.1013 1.89 (P2 + 0.1013) Q = 113S (P1 + 0.1013) Q: Air flow rate [l/min (ANR)] S: Effective area (mm) P: Differential pressure (P1-P2) [MPa] P1: Upstream pressure [MPa] P2: Downstream pressure [MPa] Correction for different air temperatures
