The issue with vacuum level
Thread Content
This post was last edited by john1628 on 2016-3-22 at 17:39. I work in the field of oxygen-enriched combustion and am studying this formula; I’m not quite sure about it. Here, Q=1200 m3/h and P=0.024 Mpa=0.24 kg/cm2. So, Q=1200/0.24=5000. In this formula, P represents vacuum pressure, but I don’t understand how this value is determined. Please help me understand this, everyone. Thank you!
This vacuum level may represent an absolute vacuum, similar to \"absolute pressure\"”； Q=1200 m3/h, it should be standard cubic. According to P1V1=P2V2, the actual flow rate Q=1200×1/0.24=5000m3/h
2L is the correct answer. The flow rate is the flow rate under standard conditions; what is calculated is the volumetric flow rate under vacuum.
