laminar flow in "vertical or inclined" pipe.
 

Hi guys
iam trying to solve this problem https://confluence.cornell.edu/downl...6935000&api=v2
i added gravity but it didn't make a difference, and the results are the same as horizontal pipe.
so what should i do ?

Did you manage to solve it?

Hi did you solve that issue??

I am sorry but i didn't manage to solve it, but one of the solutions i didn't try is changing fluid density, make it higher and see if the problem is solved.

Could you let me know how you made axisymmetric with y axis being the symmetry?
