The drop manholes are provided in a sewerage system when there is

The vertical stress at depth z, directly below the point load p is (k is a constant)

A water treatment plant is required to process 28800 m³/d of raw water (density = 1000 kg/m³, kinematic viscosity = 10^-6 m²/s). The rapid mixing tank imparts tank a velocity gradient of 900s^-1 to blend 35 mg/l of alum with the flow for a detention time of 2 minutes. The power input (W) required for rapid mixing is

Presence of excess nitrates in river water indicates :

Reaction at support b of the structure is

The superelevation needed for a vehicle travelling at a speed of 60 kmph on a curve of radius 128 m on a surface with a coefficient of friction of 0.15 is :

A vertical rod PQ of length L is fixed at its top end P and has a flange fixed to the bottom end Q. A weight W is dropped vertically from a height h(< L) on to the flange. The axial stress in the rod can be reduced by

A propped cantilever beam of span L, is loaded with uniformly distributed load of intensity w/unit length, all through the span. Bending moment at the fixed end is,

The time for a clay layer to achieve 90% consolidation is 15 years. The time required to achieve 90% consolidation; if the layer were twice as thick, 3 times forr permeable and 4 times more compressible would be :

A point load of 700 kN is applied on the surface of thick layer of clay. Using Boussinesq's elastic analysis, the estimated vertical stress (σ_v) at a depth of 2 m and a radial distance of 1.0 m from the point of application of the load, is :

The total length (in km) of the existing National Highways in India is in the range of

The dimensions for the flexural rigidity of a beam element in mass (M), length (L) and time (T) is given by

A linear relationship is observed between speed and density on a certain section of a highway. The free flow speed is observed to be 80 km per hour and the jam density is estimated as 100 vehicles per km length. Based on the above relationship, the maximum flow expected on this section and the speed at the maximum flow will respectively be

The consistency of a saturated cohesive soil is affected by

In a river, discharge is 173 m³/s; water surface slope is 1 in 6000; and stage at the gauge station is 10.0 m. If during a flood, the stage at the gauge station is same and the water surface slope is 1 in 2000, the flood discharge in m³/s, is approximately

An outlet irrigates an area of 20 ha. The discharge (l/s) required at this outlet to meet the evapotranspiration requirement of 20 mm occurring uniformly in 20 days neglecting other field losses is

The function of ballast in railaway tracks is to

A foundation is considered as shallow if its depth is :

The maximum allowable compressive stress corresponding to lateral buckling in a discretely laterally supported symmetrical I beam does not depend upon :

The soils most susceptible to liquefaction are :
