Water at 20°C is flowing through the system shown in Figure PS.45. Length AB = 2000 ft and BD = 1500 ft. All the pipes have equal diameter of 6.0 in each. The friction factor is considered to be 0.022 for all pipes. If the gage pressure at A is 90 lb/, determine the flow rate in all the pipes and pressure at points B, C, and D.
