Homework Statement
A horizontal bend in a pipeline conveys water at a discharge at 1000l/s gradually reduces from 600mm to 300mm and deflects the flow through an angle of 60 degrees. At the larger end the pressure is 170000N/m^2. Determine the magnitude and direction of the force exerted on the bend.
Homework Equations
How can I find pressure2 (at point 2 300mm end)
is my solution right to find pressure at point 2
Please help as i need solution urgently. Thanks to all
The Attempt at a Solution
I have used moment to find internal force F=DENSITY * FLOW DISCHARGE (V2-V1)
Than I have used the formula F=P/A to find the pressure.
Q(FLOW DISCHARGE) =AV (AREA*VELOCITY)
P.s if i find p2 i can use formula to find external forces on the bend using
P1A1-P2A2COSTHETA -Fx= DENSITY*Q*(V2*COSTHETA-V1)
Fy-P2A2SINTHETA= DENSITY*Q*(V2*SINTHETA)
