Regarding the issue of pipeline flow calculation
Thread Content
For a DN50 pipeline with a pressure of 6 kilograms, how is the volume of natural gas flowing per hour calculated?
Conditions are lacking; the flow rate should also be known
The conditions are insufficient; please provide a detailed description
3-8 m/s? That is 500–1350 m3/h
The answer I got is a bit different. Q = pipe cross-sectional area * flow velocity = 3.14 * (50/1000/2)^2 * (3-8) * 3600 = 21.2 m3/h – 56.5 m3/h. The formula above is generally used to calculate incompressible fluids, but gases are compressible fluids; it’s not clear whether this formula can be applied in such cases. {:3_63:} Additionally, the typical gas flow rate (at normal pressure) is listed in the manual as 10-20 m/s. @An angry young engineer in engineering
