The most appropriate triaxial test to assess the long-term stability of an excavated clay slope is

During the process of hydration of cement, due to increase in Dicalcium Silicate (C₂S) content in cement clinker, the heat of hydration

The small orifices A and B of diameter 1 cm and 2cm respectively are placed on the side of the tank at depth H₁ and H₂ below the open liquid surface. If discharge through A and B are equal. And for some value of Cd for two orifices, the ratio of H₁ and H₂ are x:1 find the value of ‘x’.

A rectangular grit chamber for a flow of 40 MLD, specific gravity 2.65 and size of the particle to be removed is 0.2mm, kinematic viscosity of liquid is 1 × 10^-2 cm² / sec, the critical horizontal velocity of flow (m/sec)_________.(round off to two decimal places)

Two points on a curve for a normally consolidated clay have the following coordinated of void ratio and pressure:

Point 1: e = 0.7 and p = 1.0 kg/cm²

Point 2: e = 0.6 and p = 3.0 kg/cm²

If the average overburden pressure on 6 m thick clay layer is 1.5 kg/cm², how much settlement will the clay layer will experience due to additional load intensity of 1.6 kg/cm²

A concrete slab of 40cm thickness has modulus subgrade reaction 90×10⁶ N/m³, then what will be the radius of relative stiffness. (Take E = 3 × 10⁵ kg/cm², poisson’s ratio μ = 0.15)

The viscous laminar flow of air over a flat plate results in the formation of a boundary layer. At the end of the plate of length ‘L’, the boundary layer thickness is ‘’. When the plate length is increased to twice its original length, the percentage change in laminar boundary layer thickness at the end of the plate (with respect to ) is………..
