In gravity dam design, the horizontal ‘silt and water’ pressure is assumed as equivalent to that of a fluid with a mass density in kg/m³ of
- A360
- B1000
- C1360Correct
- D1925
Solution
Concept
Silt and water pressure
Step-by-step solution
1. IS 6512: horizontal silt and water pressure taken as a fluid of density 1360 kg/m³.
Explanation
Combined density of water and submerged silt.
Why the other options are wrong
1000 is water only.
Shortcut
1360 kg/m³.
Correct answer: C) 1360
