The condition of stable Equilibrium of a submerged body is centre of buoyancy (B) is above the centre of gravity (G).
Stability of unconstrained Submerged Bodies in Fluid:

The equilibrium of a body submerged in a liquid requires that the weight of the body acting through its centre of gravity should be colinear with an equal hydrostatic lift acting through the centre of buoyancy.

• Stable Equilibrium: If the body returns to its original position by retaining the originally vertical axis as vertical
• Unstable Equilibrium: If the body does not return to its original position but moves further from it
• Neutral Equilibrium: If the body neither returns to its original position nor increases its displacement further, it will simply adopt its new position

The relative position of the centre of gravity (G) and centre of buoyancy (B) of a body determines the stability of a submerged body.

Stable Equilibrium: B is above G

Unstable Equilibrium: B is below G

Neutral Equilibrium: B coincides with G

• In irrigation water, the sodium permeability hazard is typically evaluated at bicarbonate and carbonate concentrations larger than 120 mg/L and 15 mg/L, respectively.
• A popular method for determining the sodium permeability danger is residual sodium carbonate (RSC), which accounts for the concentrations of calcium and magnesium in irrigation water as well as bicarbonate and carbonate.
• RSC is calculated as follows

RSC (meq/L) = (HCO₃^- + CO₃^2-) – (Ca²⁺ + Mg²⁺)
where,
RSC = residual sodium carbonate(me/l)
C0₂ = carbonate ion concentration(me/l)
HCO₃^- = bicarbonate ion concentration(me/l)
Ca²⁺ = calcium ion concentration(me/l)
Mg²⁺ = Magnesium ion concentration(me/l)
me/L = milIiequivalent/liter.

• Concerning the hazardous effects of high bicarbonate ion concentration expressed as residual sodium carbonate, the irrigation water quality rating is given in Table 3 of IS 11624- 1986

• As per IS 11624 Clause 4.1.3

  Residual sodium carbonate ( RSC ) shall be determined by the

  

Explanation:

Failure by punching:

• Punching shear is a failure mode that typically occurs in flat slabs or flat plate structures, not in columns.
• It's a failure where a concentrated load (like a column load) causes a shear failure in the concrete around the supporting column, resulting in a hole or "punching" through the slab.

Failure by elastic instability:

• This mode of failure occurs when a column becomes unstable due to buckling under axial load.
• When the axial load exceeds a critical value, the column can suddenly deflect laterally, leading to a loss of stability and collapse.

Pure compression failure:

• This mode of failure happens when a column is subjected to an axial load that exceeds its capacity to carry the load in compression.
• The concrete and steel reinforcement can fail due to excessive compressive forces, resulting in crushing of the concrete or yielding/buckling of the reinforcement.

Combined compression and bending failure:

• This mode of failure occurs when a column is subjected to both axial compression and lateral bending moments.
• The combination of these forces can lead to failure due to a combination of compressive stress and bending stress exceeding the material's capacity.

By Clause 15.2 of IS 456-2000

Sampling Procedure
A random sampling procedure shall be adopted to ensure that each concrete batch shall have a reasonable chance of being tested that is, the sampling should be spread over the entire period of concreting and cover all mixing units.

Frequency
The minimum frequency of sampling of concrete of each grade shall be in accordance with the following:

CAD (Computer Aided Design):

• CAD is the use of computers to aid in the creation, modification, analysis, or optimization of a design.
• A CAD drawing is a detailed 2D or 3D illustration displaying the components of an engineering or architectural project.
• CAD utilizes software to create drawings to be used throughout the entire process of a design project, from conceptual design to construction or assembly.

As per IRC 37:2012; the fatigue at the bottom layer of flexible pavement is given by:

Where
N_f =fatigue life in a number of standard axles
e_t = maximum tensile strain at the bottom of the bituminous layer
M_R = resilient modulus of the bituminous layer

From the above formula, it can be seen that the fatigue life of the flexible pavement depends on the following:

1. Resilient modulus of the bituminous layer
2. Maximum tensile strain at the bottom of the bituminous layer
3. The design is independent of vertical subgrade strain. It depends only on the horizontal sub-grade strain
4. Mix design of bitumen as it is dependent on the resilient modulus of the bituminous layer.

The design life and design discharge for different units in raw water are given below:

Note that:
MDD (Maximum Daily Demand) = 2 × ADD ( Average Daily Demand)

Evaporability means the ability to be evaporated i.e. change from a liquid or solid state into a vapor state.
Water evaporates at 100⁰ C.
Benzene has high vaporability than Ethyl alcohol, then water and mercury have the least vaporability.

Additional InformationBenzene (C₆H₆):

• It is a colorless liquid at room temperature (melting point 5.5 ^oC) with a density of 0.87 g/cm³ at 20 ^oC.
• It has a relatively low boiling point (80.1 ^oC) and high vapor pressure (9.95 kPa at 20 ^oC), causing it to evaporate rapidly at room temperature.
• It is slightly soluble in water (1.8 g/litre at 25 ^oC) and miscible with most organic solvents.

Concept:

Duty:

• It is the number of hectares of land irrigated for full growth of a given crop by a supply of 1 cumec of water continuously during the entire base period of that crop.

Delta:

• The total water depth required by a crop to attain its full maturity in its base period.

Base Period:

• The time period that elapsed from the instant of the showing of the crop to the instant of its harvesting is called the base period or crop period.

The relation between Duty (D), Delta (Δ) and Base period (B) is given as:

Where B = Base period (day), Δ = Delta in meter (m), and D = Duty (hectare/cumecs)

Calculation

Given,
D= 432 hectare/cumecs
B = 100 days

The relation between Duty (D), Delta (Δ) and Base period (B) is given as:

Surge Tank:

• A surge tank is a water storage device used as a pressure neutralizer in hydropower water conveyance systems in order to dampen excess pressure variance.
• A surge tank (or surge drum or surge pool) is a standpipe or storage reservoir at the downstream end of a closed aqueduct.
• A feeder dam, barrage, or pipe to absorb sudden rises of pressure, as well as to quickly provide extra water during a brief drop in pressure.
• In mining technology, ore pulp pumps use a relatively small surge tank to maintain a steady on the pump.
• For hydroelectric power uses, a surge tank is additional storage space or reservoir fitted.
• Surge tanks are usually provided in high or medium-head plants when there is a considerable distance between the water source and the power unit,

The main function of surge tanks are as follows:

• When the load decreases, the water moves backward and gets stored in it.
• when the load increases, an additional supply of water will be provided by the surge tank.
• In short, the surge tank mitigates pressure variations due to rapid changes in the velocity of the water and protects the pipeline against water hammers.

Water Hammer

• When a liquid flowing through a long pipe is suddenly brought to rest by closing the valve at the end of a pipe, then a pressure wave of high intensity is produced behind the valve. This pressure wave of high intensity has the effect of hammering action on the walls of the pipe. This phenomenon is known as a water hammer or hammer blow.

Various methods for population forecasting as suitable for that city, considering the growth pattern, are as follows:

1. Arithmetical increase method:

• In this method assumed that the population is increasing at a constant rate.
• This method is suitable for a large and old city with considerable development.

2. Geometrical increase method (or geometrical progression method):

• In this method, the percentage increase in population from decade to decade is assumed to remain constant.
• This method gives higher values and hence should be applied for a young and rapidly increasing city, but only for a few decades.

3. Incremental increase method:

• This method is a modification of arithmetical increase method.
• It is suitable for an average size town under the normal condition where the growth rate is found to be in increasing order.

4. Logistic curve method:

• This method is used when the growth rate of the population due to births, deaths, and migrations takes place under normal situation and it is not subjected to any extraordinary changes like an epidemic, war, earthquake or any natural disaster, etc.

Vertical curves:

• Valley curves or sag curves are vertical curves with convexity downwards.
• These curves are provided either when a descending gradient meets an ascending gradient or a flat gradient or a descending gradient or when an ascending gradient meets another ascending gradient.
• Valley curves are designed for two criteria: comfort and headlight sight distance.

The minimum radius of the valley curve of radius R, for a cubic parabola, is given as

Where, R = Radius of the valley, L_s = length of transition and L is the total length of valley curve (L = 2 × L_s) and N is the deviation angle

As we know that
Fixed end moments correspond to reactions at support such that the slope at supports will be zero

As conjugate beam method
The slope at supports is equal to the reaction at supports of the conjugate beam.
So we can predict that the reaction ay support of the conjugate beam is inversely proportional to the moment of inertia (MOI)
Greater MOI of the beam, lesser will be support reaction of conjugate beam hence lesser will be the slope.
So slope decreased with an increase in MOI the moment required to make slope zero will be lesser means the fixed end moment will increase.
