Flow in inclined pipe

Please login with a confirmed email address before reporting spam

I want to model laminar, Newtonian fluid flow in an inclined pipe w.r.t. gravity. The inclination angle is 30 degree. How should I define the flow? When i enter my average velocity and average pressure (atmospheric pressure) for fully developed flow my mesh doesn't form properly. Velocity - arc length graphic's values are also incorrect. Also i need to find my entrance length.
