Chapter 10, Problem 10.1CP
February 1998 saw the failure of the earthen dam impounding California Jim’s Pond in southern Rhode Island. The resulting flood raised temporary havoc in the nearby village of Peace Dale. The pond is 17 acres in area and 15 ft deep and was full from heavy rains. The breach in the dam was 22 ft wide and 15 ft deep. Estimate the time required for the pond to drain to a depth of 2 ft.

Bagnell Dam impounds the Osage River in the U.S. state of Missouri, creating the Lake of the Ozarks.
The 148-foot (45 m) tall concrete gravity dam was built by the Union Electric Company (now AmerenUE) for the purpose of hydroelectric power generation at its Osage Powerplant.
It is 2,543 feet (775 m) long, including a 520-foot (160 m) long spillway and a 511-foot (156 m) long power station. The facility with eight generators has a maximum capacity of 215 megawatts.
Using the diagram of the flow-path between the upper and lower reservoir, and assuming a flow rate of 3910 ft3/s to each generator, calculate:
a)Head loss due to viscous effect (include both major and minor losses).
b)Your estimate of the power generation capacity of an individual turbine-generator unit assuming 85% efficiency

A submerged sharp crested weir 0.81 m high stands clear across a channel having vertical sides and width of 3.15 m. The depth of water in the channel of approach is 1.26 m, and 10.5 m downstream from the weir the depth of water is 0.93 m. Determine the discharge in litres per minute. Assume Cd1 = 0.58 and Cd2 = 0.80.
After heavy rain, water flows on a concrete surface at an average velocity of 1.3 m/s. If the water depth is 2 cm, determine whether the flow is subcritical or supercritical.
