Resultant force on pipe (Fluid Mechanics)

Click For Summary
SUMMARY

The discussion centers on calculating the resultant force on a pipe using Bernoulli's Equation, specifically the formula P/pg + v1^2/2g + z1 = P/pg + v2^2/pg + z2. Participants emphasize the importance of a clear momentum balance in fluid mechanics, particularly regarding the pressure forces acting on the fluid entering and exiting the system. The conversation highlights the necessity of accurately representing momentum in the y direction to achieve correct results. Overall, clarity in calculations and exhibits is crucial for effective communication and understanding of fluid dynamics concepts.

The quality of your exhibits is very poor, but, as best I could tell, your approach is on target. But I wish I could see a cleaner rendition of your momentum balance.

Sorry about that
I think it got messed up when it was uploading.

These are my cacluations for momentum

Im thinking that I was supposed to make the momentum in the y direction negative?

I still can't read it. Did you remember to include the pressure forces on the fluid entering and leaving?
What you're trying to do is a momentum balance on the fluid passing through the y. The force of the fluid on the y is then minus the force of the y on the fluid.
