Gas pressure problems
Thread Content
I would like to know whether the pressure of gas at 0.35 MPa decreases as it flows through pipes, and what effects diameter changes, as well as the branching or merging of pipes, have on its pressure
It is inevitable for a pressure drop to occur during flow; bends, branches, and changes in pipe diameter can all affect the pressure, as explained in fluid dynamics calculations. Take another good look at the principles of chemical engineering!
As gas flows through pipes, there are frictional losses along the flow path; local resistance losses occur at points where the pipe diameter changes, or where pipes split or converge. There is a small software here for calculating pipeline losses. http://bbs.hcbbs.com/viewthread.php?tid=177091&highlight=%CB%F0%CA%A7%BC%C6%CB%E3
Thank you, I took a look. I’m not sure if the data is accurate or not, hehe
I took a look after downloading it; that calculation program is designed for water and cannot be used for gases.
