I have question that I'm sure has been asked before. Maybe if you could point me to a thread that'd be great.(adsbygoogle = window.adsbygoogle || []).push({});

The water flows steady discharging to atmosphere. I need to find the horizontal componant of force in the flanged joint & find if it's in tension or compression.

I think I have a Conservation of Momentum problem that I can't figure what I'm doing wrong. I have attached the problem. I figured that due to uniform, steady flow Q=constant so that V1A1=V2A2. So with that I plugged into the momentum flux equation.

=density of water((v2^2)(A2)(cos30)-(V1^2)(A1))+(Pressure)(A2)

If it discharges to atmosphere then I thought maybe it's Pressure(gage)(A1) instead of A2? I think I'm all over the place with this one.

Thanks for any assistance clearing the fog
