Fluid Mechanics - Determine the Magnitude and Direction of the Anchoring Force

Fluid Mechanics 5.45

Determine the magnitude and direction of the anchoring force needed to hold the horizontal elbow and nozzle combination shown in place. Atmospheric pressure is 100 kPa(abs). The gage pressure at section (1) is 100 kPa. At section (2), the water exits to the atmosphere.

Thank you so much for explaining every detail profs neglect to go over. The details are critical to understanding. This video alone solidified my understanding largely.

Thank you, you saved me. YOU ALREADY KNOWWW!!

Go to 3:05 to see why we use gage pressure for these problems, and not absolute.

this is really late but could someone explain why there is zero y direction force? I had this problem and I was wondering why we ignore weight/mass, the upward movement of the water, etc. Is it just assumptions we make and what is the reasoning because surely there is some force on the connections? Is it just negligible in comparison to the x component?

Why are inlets negative and outlets positive? Is it the mass flow rate?

How did you come up with the eqn in step 5, could you do a step by step break down

Hii can I know why P1A1 and P2A2 are positive?
