An engineer proposes as a solution to the problem of the dam, to reinforce it according to the figure shown, but now the critical height h of the water level must be determined, which would make the indicated concrete reinforcement on the verge of overturning due to the water pressure.

Since there is a need to supply more water from reservoir A to reservoir B, it is necessary to lay an additional pipe parallel to it. The existing pipe is 0.6m in diameter with a discharge of 0.5m³/sec between the two reservoirs and 6000m long. Assume f = 0.02 %3| for the old pipe and f = 0.25 for the additional pipe. Determine the following: %3D a. If the additional pipe will have a discharge of 0.65m³/sec of the same length and the head difference between the two reservoirs is constant, find the pipe diameter. ANSWER: h= 25m Existing Pipe Q=0.50m³/sec D = 0.697 m в Additional Pipe b. If the additional pipe of 0.6m in diameter is laid out from the original pipe at its midpoint towards reservoir B, find its capacity. Assume f = 0.02. Also solve for the change in the %3D flow or discharge from A to B. ANSWER: Existing Pipe h=25m QA = 0.7232m/s, QB = 0.3923m³/s, %3D AQ = QA – Q = 0.5271m³/s %3D | в `Additional Pipe
