Technical Mock Test CE (SSC JE)- 17 - Question 101

In which soil structure are the particles arranged more or less parallel to each other?

Detailed Solution for Technical Mock Test CE (SSC JE)- 17 - Question 101

Dispersed Structure: In the case of dispersed structure, the particles will have face to face contact. This type of formation is due to net electrical forces between adjacent soil particles at the time of deposition being repulsive in nature. This type of structure is common in fresh water deposits.

Flocculated Structure: In the case of flocculated structure there will be edge to edge and edge to face contact between the particles. This type of formation is due to the net electrical forces between the adjacent particles at the time of deposition being attractive in nature.

Honeycomb Structure: This type of structure is associated with silt deposits. When silt particles settle out of suspension, in addition to gravitational forces the surface forces also play a significant role.

When particles approach the lower region of suspension they will be attracted by particles deposited as well as the neighbouring particles leading to the formation of arches.

Single grained: This type of structure will be found in the case of coarse grained soil deposits. When such soils settle out of suspension in water, the particles settle independently of each other.

The major force causing their deposition is gravitational and surface forces are too small to produce any effect.

There will be particle-to-particle contact in the deposit.

Technical Mock Test CE (SSC JE)- 17 - Question 132

Which one of the following is relatively more accurate estimating method for building?

Detailed Solution for Technical Mock Test CE (SSC JE)- 17 - Question 132

Elemental bill method: This estimate requires more information other than floor areas. To use this method, drawings with enough information are required i.e. wall elevations, structural frame, roof structure, ceilings, foundation cross sections, floor construction, external works, wall and floor finishes.

The document contains detailed information broken down into Building Elements.

Cubic method of Estimating: The cube method estimating is a single rate method of estimating based on the cubic content of a building.

Cost per cubic metre method is specific for building projects and aims to overcome the current criticism floor area method that does not take into account possible variations of the storey height.

The building volume method became very popular in some European countries like in Germany and Switzerland, where building costs are often expressed in cubic meter prices. The total cost of the project will be given by:

Estimate = Volume X Unit Cost (Cost/m3)

Square meter method of estimation: The superficial floor area also known as the square metre method of estimating is one of the quickest methods of calculating the cost of a building/construction project.

It is the first estimate that will be prepared by a Quantity Surveyor when initial sketch drawings are produced by the architect.

The square metre method involves measuring the internal gross floor area of a building and multiplying by the cost per m2, to get the total cost of building.

Service unit method: The unit method estimating consists of choosing a standard unit of accommodation and multiplying an approximate cost per unit. Estimate the building cost depends on the population unit.

The unit cost method of estimation is used for project design estimates and bid estimates.

Unit Method Estimate = Standard units of accommodation x Cost/Unit

Technical Mock Test CE (SSC JE)- 17 - Question 137

Inclined manometer is used for precise measurement of small pressure in:

Detailed Solution for Technical Mock Test CE (SSC JE)- 17 - Question 137

For accurate measurement of small pressure differences by an ordinary u-tube manometer, it is essential that the ratio ρmw should be close to unity.

This is not possible if the working fluid is a gas, also having a manometric liquid of density very close to that of the working liquid and giving at the same time a well-defined meniscus at the interface is not always possible. So, for this purpose, an inclined tube manometer is used.

For low velocity gas flow, inclined manometers are best suitable for precise measurement of small pressure.

Technical Mock Test CE (SSC JE)- 17 - Question 138

Separation of flow occurs when pressure gradient:

Detailed Solution for Technical Mock Test CE (SSC JE)- 17 - Question 138

Flow separation occurs when the boundary layer travels far enough against an adverse pressure gradient that the speed of the boundary layer relative to the object falls almost to zero.

It has been observed that the flow is reversed at the vicinity of the wall under certain conditions.

favourable pressure gradient is one in which the pressure decreases in the flow direction (i.e., dp/dx < 0). It tends to overcome the slowing of fluid particles caused by friction in the boundary layer.

This pressure gradient arises when the freestream velocity U is increasing with x, for example, in the converging flow field in a nozzle.

On the other hand, an adverse pressure gradient is one in which pressure increases in the flow direction (i.e., dp/dx > 0). It will cause fluid particles in the boundary-layer to slow down at a greater rate than that due to boundary-layer friction alone.

If the adverse pressure gradient is severe enough, the fluid particles in the boundary layer will actually be brought to rest. When this occurs, the particles will be forced away from the body surface (a phenomenon called flow separation) as they make room for following particles, ultimately leading to a wake in which flow is turbulent.

Due to sudden contraction, the loss of head occurs due to sudden contraction of pipe, therefore total energy decreases.

As due to contraction, area of pipe decreases due to which velocity increases, thereby velocity head increases.

As the increase in velocity head will lead to decrease in Pressure head or we can say that conversion of velocity head to pressure head occurs.

Technical Mock Test CE (SSC JE)- 17 - Question 145

For crops like potato and sugar-beets, the commonly adopted method of surface irrigation is:

Detailed Solution for Technical Mock Test CE (SSC JE)- 17 - Question 145

Furrow Irrigation: In this type of irrigation, only one-fifth to one-half of the land surface is wetted by water. It therefore results in less evaporation, less pudding of soil and permits cultivation sooner after irrigation.

When crops like potatoes, corn, sorghum and sugar beets are grown, it is usually best to irrigate by the furrow method.

Check flooding: Check flooding is similar to ordinary flooding except that the water is controlled by surrounding the check area with low and flat leeves.

Drip irrigation: Drip irrigation is the latest field irrigation technique which is meant for adoption at places where there exists acute scarcity of irrigation water and other salt problems. Water is slowly and directly applied to the root zone of the plants, thereby minimising the losses by evaporation and percolation.
