he support bracket for a water pipe that brings water from the city water systeminto the basement of DeMoss Hall needs to be replaced since it was originally improperlydesigned. An ENGR 315 class is contracted to determine the proper forces in the x and ydirection on the redesigned support at C. Water from the city line flows into DeMoss Hall in a 2-inch diameter pipe at A at 20 ft/sec and pressure 20 psi. The weight of the piping system andenclosed water is 110 lbf. The specific gravity of the water is 62.4 lbf/ft3. There are no minor ormajor losses used in the system analysis. Determine the x (horizontal) and y (vertical)components at support C. The figure is based on a vertical view of the system.
