The correct answer is D. Method of projection

Estimating building works involves various methods such as the long wall-short wall method, centerline method, and partly centerline and partly cross wall method. However, the method of projection is not recognized as a standard technique for estimating building works. The long wall-short wall method calculates wall lengths based on their orientation in a room, while the centerline method focuses on walls with similar cross-sections, adjusting for junctions. The partly centerline and partly cross wall method combines these approaches for walls of varying thicknesses, making them all valid methods for estimation.

Details on Other Options:

• A: The crossing method is a valid technique for estimating areas and quantities in building works, often used in conjunction with other methods.
• B: The out-to-out and in-to-in method is a recognized approach for calculating dimensions and materials needed for construction, specifically addressing wall thickness.
• C: The centerline method is a common estimation technique for walls of similar cross-sections, ensuring accurate measurement by adjusting for junctions.

Conclusion:

Option: D, as the most accurate and relevant option, stands out for its non-recognition in standard estimating methods, clearly differentiating it from the other techniques. Thus, Method of projection is the correct choice.

Secondary pollutant:

• The primary pollutants often react with one another or with water vapor, aided and abetted by the sunlight, to form entirely a new set of pollutants, called the secondary pollutants.
• These are the chemical substances, which are produced from the chemical reactions of natural or anthropogenic pollutants or due to their oxidation, etc., caused by the energy of the sun.

Examples:
1) Sulphuric acid (H2SO4)
2) Formaldehydes
3) Photochemical smog
4) Ozone
5) Peroxy Acetyl – nitrate (PAN)

Primary pollutant:

• Pollutants are emitted directly from identifiable sources, either from natural hazardous events like dust storms, volcanoes, etc, or from human activities like burning of wood, coal, oil in homes or industries or automobiles, etc.

Examples:
1) SO2
2) CO & CO2
3) NO, NO2
4) Volatile organic compound
5) Suspended Particulate Matter (SPM)
6) Radioactive compound
7) Halogen compound

Concept:

Traverse reinforcement/ties are provided in columns for the following reasons:

i) To prevent the premature buckling of individual bars.

ii) To confine the concrete in the 'core', thus improving ductility and strength.

iii) To provide resistance against shear and torsion is required.

iv) To hold the longitudinal bars in position during construction.

Therefore, one of the purposes of the provision of lateral ties in columns is to avoid buckling of longitudinal bars.

Plumb bob and plumb fork:

• A plumbing fork is a hairpin-shaped brass frame made of arms of equal length.
• One is horizontal (upper arm) has a pointed end and is kept over the drawing sheet touching the plotted position of the instrument station while the other is inclined at a certain angle(lower arm) has a hook from which plumb bob is suspended as shown in the figure.

∴ Hence accurate centering of the plane table is done by using a plumbing fork.

Concept:

Lacey gave three independent equation after intensive research in alluvium and gave the idea of regime.

The equations given by Lacey are:

As per lacey, the wetted perimeter P is given as

P = 4.75 √Q

Hence the wetted perimeter of the alluvial channel increases with an increase in design discharge.

Important Point:

Difference between Lacey and Kennedy theory are:-

Afflux:
(i) Afflux is an increase in water level that can occur at upstream of a structure, such as a dam, bridge, or culvert, that creates an obstruction in the flow.

(ii) On the upstream side of the dam, the depth of the water will be rising due to the obstruction/barrier. If there had not been any obstruction (such as dam) in the path of the flow of water in the channel, the depth of water would have been constant parallel to the bed of the channel. Due to obstruction, the water level rises, and it has maximum depth from the bed in some sections.

(iii) This rise of water level on the upstream end is termed as afflux.

Given,
Head(H) = 10 m, Discharge(Q) = 500 cumec
Diameter (D) = 9 m
We know Q = A × V ⇒ Area (A) ∝ D² , Velocity (V) ∝ √H
∴ Q ∝ D2√H

For Unit discharge


Q_u = 1.952
∴ Unit Discharge Q_U = 1.952

Statement 1:
Sprinkler irrigation is more suitable than surface methods when the land has very pervious soil and an undulated surface profile. This statement is correct. Sprinkler irrigation can be advantageous on lands with very pervious soil as it helps to overcome excessive water infiltration and allows for more efficient water application. Additionally, the ability to adjust sprinkler heads can accommodate an undulated surface profile for better water distribution.

Statement 2:
Sprinkler irrigation is more suitable than surface methods when the land has steep slopes. This statement is correct. Sprinkler irrigation is often preferred over surface methods, such as furrow or flood irrigation, when the land has steep slopes. Surface methods may result in excessive runoff and erosion on steep slopes, whereas sprinkler irrigation can provide more controlled water application, reducing runoff and soil erosion.

Therefore, Both statements are correct.

Irrotational flow:

• Irrotational flow is a flow in which no element of the moving fluid rotates in any direction from one instant to the next. Therefore, only a torque applied by shear forces on the sides of a fluid particle can cause it to rotate.
• Irrotational flow occurs when all of the tiny particles of fluid move along, translate, go around obstacles, and so on without ever rotating about their own infinitesimal centres of gravity. Irrotational flow can only continue if there is no viscosity.
• Because shear forces do not exist in ideal fluids, their flow is essentially irrotational. When a flow is viscid, it tends to become rotational. This is because viscosity causes velocity gradients, as well as distortion and rotation of fluid particles, despite the fact that the fluid as a whole does not need to rotate around a fixed centre. When the vorticity is zero everywhere, the flow is said to be irrotational.

Various type of the beam and their purpose:

Transition curve is provided to change the horizontal alignment from straight to circular curve gradually and has a radius which decreases from infinity at the straight end (tangent point) to the desired radius of the circular curve at the other end (curve point). Cubic parabola, spiral and Lemniscate are typically used as transition curves.

There are five objectives for providing transition curve and are given below:
1. to introduce gradually the centrifugal force between the tangent point and the beginning of the circular curve, avoiding sudden jerk on the vehicle. This increases the comfort of passengers.
2. to enable the driver turn the steering gradually for his own comfort and security,
3. to provide gradual introduction of super elevation, and
4. to provide gradual introduction of extra widening.
5. to enhance the aesthetic appearance of the road.

Head loss in the pipe due to friction is given as:

where f = friction coefficient, 4f = friction factor, V = average velocity of flow, D = diameter of pipe, l = length of pipe
V = Q/A
where Q = flow rate, A = Cross Area of pipe
∴ head loss ∝ V², head loss ∝ Q², head loss ∝ l,

Alternate Method

We know that,

Concept:
Characteristics Ultimate load method (ULM): -
1. It is also known as Load factor method or ultimate strength method.
2. The safety measure in the design is introduced by an appropriate choice of the load factor, which is defined as the ratio of ultimate load (design load) to the working load.
3. The satisfactory ‘strength’ performance at ultimate loads does not guarantee satisfactory ‘serviceability’ performance at the normal service loads.
4. This method results in more slender sections compared to WSM.
Hence,
The design load will be equal to working load multiplied by a load factor.

Concept:

Properties of Stones:

The following are the engineering and physical properties of the stones that should be looked into before selecting them for engineering works:

1. Structure:

1. The structure of the stone may be stratified (layered) or unstratified.
2. Structured stones should be easily dressed and suitable for the superstructure.
3. Unstratified stones are hard and difficult to dress. They are preferred for foundation works.

2. Texture:

• Fine-grained stones with homogeneous distribution look attractive and hence they are used for carving.
• Such stones are usually strong and durable.

3. Density:

• Denser stones are stronger.
• Lightweight stones are weak. Hence stones with a specific gravity of less than 2.4 are considered unsuitable for buildings.

4. Appearance:

• A stone with a uniform and attractive colour is durable if grains are compact.
• Marble and granite get a very good appearance, when polished. Hence they are used for face works in buildings.

5. Strength:

• Strength is an important property to be looked into before selecting stone as a building block.
• Indian standard code recommends, minimum crushing strength of 3.5 N/mm² for any building block.

Concept:

Statement 1-

• In a steel compound column section, the width will be smaller when they are placed face to face than when they are placed back to back.
  
• When the columns are placed face to face the spacing between the columns will be less to get the moment of inertia equal to the moment of inertia about the horizontal axis. As the spacing will be less the width will be smaller.
• So statement 1 is correct.

Statement 2-

• In the design of steel compound columns, the length of battens are normally lesser than the lacings.
• As the battens are horizontal elements while lacings are inclined elements so the length of lacing will be more.
• So statement 2 is wrong.

Statement 3-

• Lacings in a steel compound column are designed as slender compression members.
• Lacings are the members that undergo only axial compressive force whereas battens undergo both bending moment and shear forces so lacings are designed as slender compression members.
• So statement 3 is correct.

Concept:

1) Vee-Bee consistometer test is used for the concrete which possess low workability, slump for which is limited to 50 mm.

• The measurement of the effort is done by time measurement in seconds. The amount of work measured in seconds is called as the remolding effort. The time required for the complete remolding is a measure of the workability and is expressed in the Vee-Bee seconds.

2) Air permeability method (Blaine)

• The fineness of cement is measured as the specific surface. Specific surface is expressed as the total surface area in square meters of all the cement particles in one kilogram of cement. The higher the specific surface is, the finer cement will be.
• The fineness test is performed on the Blaine apparatus. It is practically a manometer in the U-tube form. One arm of the manometer is provided at the top with a conical socket to form an airtight fit with the conical surface of the cell.

3) Standard consistency test:

• This test determines the percentage of water required to make workable cement paste.
• Vicat’s apparatus is used to perform this test
• Temperature during test = 27 ± 2°C, Relative humidity = 90%
• As per Vicat’s test ‘the percentage of water added to the cement at which the needle cannot penetrate 5-7 mm from bottom of the mould is called consistency.
• For OPC consistency is around 30%

In order to make a cement paste of normal consistency the percentage of water varies from 25 to 35%.

4) Le Chatelier Test:

• This test is used to measure the soundness of OPC due to lime. Lime & Magnesia are two primary compounds responsible for the soundness of cement.

5) Cone slump test

• This is used to find the workability of the concrete not setting time

Concept:
Conjugate beam:

1. A conjugate beam is an imaginary (hypothetical) beam of the same (equal) dimensions as the original beam with a different loading configuration.
2. The load on the conjugate beam is the M/EI diagram of the loads on the actual beam.
3. A simple support for the real beam remains simple support for the conjugate beam.
4. A fixed end for the real beam becomes a free end for the conjugate beam.
5. Then the shear force at any point on the conjugate beam gives the slope at the corresponding point of the actual beam.
6. The B.M. at any point on the conjugate beam gives the deflection at the corresponding point of the actual beam.
7. The point of zero shear for the conjugate beam corresponds to a point of zero slope for the real beam.
8. The point of maximum moment for the conjugate beam corresponds to the point of maximum deflection for the real beam.

​Both statements are correct. Hence option (2) is correct.

The average permeability for flow perpendicular to the bedding planes is given by,

The average permeability for flow parallel to the bedding planes is given by,

∴ Average permeability for flow perpendicular to the bedding plane is harmonic mean whereas, average permeability for flow parallel to the bedding plane is the arithmetic mean. As arithmetic mean is always greater than harmonic mean therefore, the average permeability for flow perpendicular to the bedding plane is always lesser than the average permeability for flow parallel to the bedding plane.

Creep of rail:
Creep is defined as the longitudinal movement of the rail with respect to the sleepers. Rails tend to gradually move in the direction of dominant traffic.
Theories for the development of creep

1) Wave motion theory:
According to this theory the rails have a wavy formation, as the wheels move forward, the depression also moves with them and the previously depressed portion springs back to the original one.

2) Percussion theory:
According to this theory, creep is developed due to the impact of wheels at the rail end ahead of the joint. The continuous movement of several wheels passing over the joint pushes the facing or landing rail forward, thereby causing creep

Major causes for creep in rail are as follows:
a) Forces developed when the train is starting or stopping by application of brakes.
While starting, the wheels push the rail backwards and hence the direction of creep is in the backward direction.
When brakes are applied then the wheels of the vehicles push the rails in the forward direction and hence the creep is in the forward direction.
b) Due to wave motions developed when the wheels of the vehicle hit the crest.
c) Unequal expansion/contraction due to the different temperature gradients along the track.
