Fluid Mechanics Dams - Problems And Solutions Pdf

A trapezoidal dam (concrete, ( \rho_c = 2400 , \textkg/m^3 )) has height 40 m, crest width 5 m, base width 30 m, water depth 40 m. Ignoring uplift, find FS against overturning about toe. (Hint: Divide trapezoid into rectangle + triangle, compute weights and moments) Answer: FS ≈ 2.1 (depends on exact geometry).

As water rushes down a spillway, it reaches high velocities. If this energy isn't managed, it will erode the "toe" (bottom) of the dam, leading to structural failure. The Solution: fluid mechanics dams problems and solutions pdf

Evaluating the moments about the "toe" of the dam to ensure it won't rotate. A trapezoidal dam (concrete, ( \rho_c = 2400

The moment created by water pressure must be countered by the moment created by the dam's weight. : Usually required to be >1.5is greater than 1.5 ⚡ Sliding
