engineering recuitment UKPSC AE Civil 2021 Mock Test (Re-Exam) Irrigation Engineering Dams and Spillways
The base width of an elementary profile of a gravity dam of height H is b. The specific gravity of the material of the dam is G and uplift pressure coefficient is K. The correct relationship for no tension at the heel is given by
1
\(\frac{b}{H} = \frac{1}{{\sqrt {G - K} }}\)
2
\(\frac{b}{H} = \sqrt {G - K} \)
3
\(\frac{b}{H} = \frac{1}{{G - K}}\)
4
\(\frac{b}{H} = \frac{1}{{K\sqrt {G - K} }}\)
