Fluid Mechanics Dams Problems And Solutions Pdf Fixed

. To solve these, you must account for the dam's weight, the pressure exerted by the water, and potential uplift forces at the base. Core Principles for Dam Analysis Dams are typically analyzed using a one-meter strip (unit width) to simplify calculations. Hydrostatic Force ( cap F sub h The horizontal force exerted by water. is the specific weight of water ( is the depth to the centroid, and is the submerged area. Line of Action: Acts at a height of from the base. Weight of the Dam ( The vertical force providing stability. Hydrostatic Uplift ( Upward pressure from water seeping under the foundation. Factors of Safety (FS): Against Sliding: is the friction coefficient. Against Overturning: Sample Problem: Gravity Dam Stability A concrete gravity dam has a height of and a rectangular cross-section

wide at the base (triangular section). If water is at the top, find the factor of safety against overturning. Water Force ( cap F sub cap H Overturning Moment ( cap M sub cap O Dam Weight ( Resisting Moment ( cap M sub cap R (Likely unsafe, as it is below the typical threshold).
