A pipeline connected to a reservoir discharges water 30 m below the free surface in the tank. The pipeline crosses a ridge whose summit is 9 m above the level of free surface and 300 mm distant from the reservoir. The pipe is 0.6 m in diameter and 3 000 m long and the connection is sharp and sudden. Take ƒ = 0.0075. Finda, the minimum depth below the ridge at which the pipe must be laid, if the absolute pressure in the pipe is not to fall below 3 m of water.b, the discharge
A masonry dam of trapezoidal cross section, withone face vertical has a thickness of 60 cm at the top,3.70 m at the base, and has a height of 7.40 m.What is the depth of water on the vertical face ifthe resultant intersects the base at the downstreamedge of the middle third? Assume that the upliftpressure varies uniformly from full hydrostatic atthe heel to zero at the toe. Follow the steps: Step 1. Solve for all the forces. Step 2. Solve for Rx and Ry. Step 3. Solve for RM and OM. Step 4. Solve for x, where we will get the value of h or the depth of water. Note: The answer must be near or exactly 5.83m.
