Dear Dejan, Thank you so much for your explanation and link sites.
I will calculate dynamic volumetric flow with vary opening ball valve because i will create dynamic flow simulation for this case. I will try to use the formula as your advice from the site (Mass Flow through Nozzles): mc = Ac (n...
Hi,
I’m new in engineering.
I would like to calculate dynamic flow and pressure of natural gas (MW= 19.8; Density (Kg/m3) = 59) with data as below:
Point 1 (Piping): P1 = 72 barg; T1 = 41 oC; D1 = 36 inch.
Point 2 (Ball valve (as of bypass valve): Size = 2 inch
Point 3 (Piping (closed pipe))...
