CE HPGE Past Board Exam Objective Type Questions

Surface tension

The elastic tendency of liquids which makes them acquire the least surface area possible. It is responsible, for example, when an object or insect such as mosquitoes that is denser than water is able to float or run along the water surface.

Degree of saturation

The ratio between the volume of water and the volume of voids.

Porosity

The ratio between the volume of voids and the volume of the soil mass.

Moisture content

The ratio between the weight of water and the weight of solid particles.

Archimedes

Which of the following states the law of buoyancy?

Steady flow

A flow in which the velocity of the fluid at a particular fixed point does not change with time.

Cohesion

Which component of rock or soil is independent of interparticle friction?

Liquefaction

A phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading.

Effective stress

A pile of sand keeps from spreading out like a liquid because the weight of the sand keeps the grains stuck together in their current arrangement, mostly out of static friction. This weight and pressure is called:

Gas

Which of the following is not a soil component?

Sieve analysis

A practice or procedure used to assess the particle size distribution (also called gradation) of a granular material. The size distribution is often of critical importance to the way the material performs in use.

Gravel

According to USCS, what do you call a soil grain with grain size greater than 4.75 mm but less than 75 mm?

None of these

Which of the following does not affect the settlement of a footing?

Turbulent

When the path lines of the individual particles of a flowing liquid are irregular curves and continually cross each other and form a complicated network, the flow is called:

Hydraulic gradient

A line joining the points of highest elevation of water in a series of vertical open pipes rising from a pipeline in which water flows under pressure is referred to as:

Water hammer

A pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly (momentum change) is referred to in hydraulics as:

4°C

At what temperature (°C) at which liquid water has the highest density?

Pascals

The pressure exerted onto a liquid is transmitted equally and undiminished to all portions of the liquid. This principle in fluid mechanics is known as:

Bernoulli

In any stream flowing steadily without friction the total energy contained in the same at every point in its path of flow. This principle is attributed to:

Possess low shear strength

Which of the following is not a characteristic of a cohesive soil?

Porosity

The ratio of the volume of voids to the total volume of soil.

In standard penetration test, medium dense sand have number of blows of:

Sand

In accordance with the USCS, a soil grain having a size greater than No. 200 sieve opening (0.074 mm) but less than that of a No. 4 sieve (4.75 mm opening) is called:

10 to 30

A granular soil deposit is considered medium dense if the blow count of a standard penetration test is between:

Decreases

If the ground water table in a soil formation rises as a result of flooding, the bearing capacity of the soil:

Cobble

According to USCS, particles with size greater than 75 mm are called:

Steady

A type of flow where at any instant, the amount of fluid particles passing through a pipe section is constant.

Water hammer

A pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly (momentum change) is referred to in hydraulics as:

Hydraulic grade line

A line joining the points of highest elevation of water in series of vertical open pipes rising from a pipeline in which water flows under pressure.

Decreases

If the ground water table in a soil formation rises as a resulting of flooding, the bearing capacity of the soil:

Load imposed onto the soil

One of the following foundation conditions does not affect the bearing capacity of the supporting soil:

Liquefaction

This occurs when a cohesionless saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liquid.

Conservation of mass

On what fundamental concept is the continuity of flow primarily based?

Hydrodynamics

A branch of fluid mechanics that deals with the study of forces exerted by liquids in motion.

All of these

The total pressure force on a plane surface is equal to the area multiplied by the intensity of pressure at the centroid if the surface is:

Water hammer

A pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly (momentum change) is referred to in hydraulics as:

Long pipe

Which of the following is not affected by minor loss?

Shear vane test

Which of the following shear tests of soil is not performed in a laboratory?
