- Determine the wet unit weight in (kN/m³) Show solutions please. Thankyou :)Please give proper solution other wise skip I want to learn. A Masonry dam 8 m high, 1.5 m wide at top and 5 m wide at the base retains water to a depth of 7.2 m, the water face of the dam being vertical. Find maximum and minimum stress intensities at the base. The weight of water is 9.81 kN/m³ and weight of masonry is 22 kN/m².Calculate for the liquid pressure experienced using the equation: P=pgh solve in GRESAJ format height = 7.10 feet Flood density is generally assumed to be 62.4 g/mL regardless of the amount of debris. Cement can withstand a pressure of ≈ 28728.2 Pa.

- what are the problems encountered in concrete caisson (25 ft dia) process up to a depth of 50 ft on the rock surface. explain with the help of diagram.Pls answer, I'll rate. A concrete dam retaining water is shown. If the specific weight of concrete is 150 ??⁄??3, and the coefficient of friction between the base of the dam and the foundation is 0.42. Calculate the height of the dam that is necessary to prevent the dam from sliding. Use 1.5 as the factor of safety (F.S) against sliding.A cross-section of a concrete gravity dam is shown in figure. Analyze the stability of block A for empty and full upstream reservoir cases, separately. Ignore earthquake, silt wave and ice forces. Specific weights of concrete and water are 23kN/m3and 10kN/m3, respectively. Compressive and shear strengths of concrete are 35MPa and 6MPa, respectively. The coefficient of friction between concrete blocks is 0.65. There is no tail water in downstream. Safety factors will be ≥2 for overturning, will be ≥1.5 for sliding and will be ≥3 for shear sliding.
