Question
The bend is connected to the pipe at flanges A and B as shown. The diameter of the pipe is 1 ft. The total weight of the bend and the water within it is 500 lb, and the mass center is at point G. The pressure of the water at A is 15 psi. The velocity profile at cross-section A is given by 
V(r) = 127.32 * (1-(r/R)^2) ft/s
where r is the radial distance measured from the center of the pipe. Assume that no force is transferred to the flanges A and B. Answer the following questions:
a.) Determine the average velocity and the volumetric flowrate through the bend.
b.) Determine the pressure at B.
