A 1000-ft-long 2-ft-diameter concrete pipe (sharp-edge entrance) is used to convey 60F water from Reservoir A to B. At the end of the pipe, a diffuser with an exit diameter of 3.5 ft is installed to reduce discharge loss. If the friction loss in the diffuser is negligible, determine the flow rate in the pipe. Consider the expansion loss of the diffuser as the difference of the pre- and post-expansion velocity heads. 200 ft Reservoir A D=2 ft, L= 1000 ft V 100 ft 3.5 ft Reservoir B hapo
