A one-dimensional consolidation test is carried out on a standard 19 mm thick clay sample. The oedometer's deflection gauge indicates a reading of 2.1 mm, just before removal of the load, without allowing any swelling. The void ratio is 0.62 at this stage. The initial void ratio (round off to two decimal places) of the standard specimen is _______.

Ques 34 Civil

Velocity distribution in a boundary layer is given by u / u_∞ = sin((π/2)(y/δ)), where u is the velocity at vertical coordinate y, u_∞ is the free stream velocity and δ is the boundary layer thickness. The values of u_∞ and δ are 0.3 m/s and 1.0 m, respectively. The velocity gradient (∂u/∂y) (in s^-1, round off to two decimal places) at y = 0, is _______.

Ques 35 Civil

Two identically sized primary settling tanks receive water for Type-I settling (discrete particles in dilute suspension) under laminar flow conditions. The Surface Overflow Rate (SOR) maintained in the two tanks are 30 m³/m².d and 15 m³/m².d. The lowest diameters of the particles, which shall be settled out completely under SORs of 30 m³/m².d and 15 m²/m².d are designated as d₃₀ and d₁₅, respectively.
