The distilled water exit the desalination unit through a pipe at a rate of Qmain andpressure Pmain, branches out into two pipes at right angles, each carrying half thetotal flow, as shown in the plan view below. The diameter of the main pipe is dmainand the diameter of the two smaller pipes is dbranch. If the space ABCA is filled witha filler material, calculate the total reaction force generated by the filler to resistthe forces acting on the bends of the branching pipes.
