The lateral pressure exerted by paddy on the bin wall, as computed by Rankine's formula, was \(6000 \text{ kgf/m}^2\) when the pressure coefficient is 0.5. What would be the height of bin if the density of paddy is \(600 \text{ kg/m}^3\)

According to Janssen theory, the lateral pressure exerted by the grain on the wall is influenced by -
(A) Pressure coefficient
(B) Shape of grain
(C) Bulk density of grain
(D) Depth of grain

27. Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Direct shear test is not of much use for fine grained soils where drainage conditions play an important role influencing the shear strength.
Reason (R) : In direct shear test drainage conditions can not be controlled and pore water pressure can not be measured.
