A borrow pit soil has a dry density of 17 kN/m^{3}. How many cubic meters of this soil will be required to construct an embankment of 100 m^{3} volume with a dry density of 16 kN/m^{3}.

The ultimate bearing capacity of a soil is 300 kN/m^{2}. The depth of foundation is 1 m and unit weight of soil is 20 kN/m^{3}. Choosing a factor of safety of 2.5, the net safe bearing cacpacity is

For a body floating in a liquid the stability is ensured if the centre of buoyancy and the centre of gravity, regardless of the relative positions of the centre of buoyancy and gravity

For a body floating in a liquid the stability is ensured if the centre of buoyancy is below the centre of gravity and the metacentre is above both the centres of gravity and buoyancy.

Answer: Option D

Explanation:

No answer description available for this question. Let us discuss.

The flow of water (mass density = 1000 kg/m^{3} and kinematic viscosity = 10^{-6} m^{2}/s) in a commercial pipe, having equivalent roughness k_{s} as 0.12 mm, yields an average shear stress at the pipe boundary = 600 N/m^{2}. The value of k_{s}/δ' (δ' being the thickness of laminar sub-layer) for this pipe is
