hi @jousefm, and thank you for trying to help me out with this problem.

I had no luck with figuring out my current simulation. So i have decided to simplify it and just model a vertical 20" in diameter and 11 ft long pipe. I am still looking for pressure and velocity distribution along the pipe. I am hoping that the simplified model would make it easier to figure out how to account for elevation change in the model. This it the link to the new simulation:https://www.simscale.com/workbench/?pid=8362338750270950273&mi=spec%3A13d5d872-08e8-47fa-b42f-24fb47ab96f1%2Cservice%3AMESHING%2Cstrategy%3A2

I am keeping most of my assumptions the same such as 10 psi for the top face of the pipe, incompressible and turbulent flow. And 15.5 psi for the bottom face of the pipe.

Can you possibly take a look at it as well and let me know how can I account for the elevation change in the pipe?

Any help you can provide to me would be greatly appreciated.

Thank you,

Maria Chek
