The figure below, shows part of a larger pipe network. Pipes 1 and 4 have diameter of 4 feet, length of 1800 feet, and carry a flow of 120 cubic feet per second. Pipe 2 is 1500 feet long and has a diameter of 3 feet. Pipe 3 has a length of 1500 feet and a diameter of 2 feet. Assume that the Hazen-Williams coefficient for all pipes is CHW = 100 and neglect minor losses. Determine the total head loss due to friction between points A and D. where points A and B are connected by pipe 1 and points C and D are connected by pipe 4
