Calculation of gas critical flow velocity

2012-05-31View Original

Thread Content

Question: A pipeline carries compressible gas; the outlet is a small orifice with a fixed cross-sectional area, while the inlet pressure is adjustable. How can the maximum flow velocity that the gas can reach be calculated? What happens to the gas flow rate when pressure is increased further after reaching the maximum flow velocity?

Isn’t the maximum flow velocity of a gas the speed of sound? Vc= ^0.5=316.2* m/s Ludwig’s Applied Process Design for Chemical And Petrochemical Plants, Volume 1
