Gentrification is the process whereby the character of a poor urban area is changed by wealthier people moving in. improving housing, and attracting new businesses, often displacing current inhabitants in the process. Gentrification is the transformation of a city neighbourhood from low value to high value.

Given;

Distance = 600 m

Slope = 1: 10

Rise = distance / slope

= 600 / 10 = 60

Contour interval = rise / number of contours -1

= 60 / (6 - 1) = 12 m

As per the standards of Handbook on Barrier Free and Accessibility, CPWD, 2014; the maximum gradient of a ramp can be 1 in 12. This means a rise of 1 meter will require a run of 12 meter. In this question, run given is 6 meter; so rise will be 0.5 meter or 50 cm.

Parties with commitments under the Kyoto Protocol (Annex B Parties) have accepted targets for limiting or reducing emissions. These targets are expressed as levels of allowed emissions, or assigned amounts, at over the 2008-2012 commitment period. The allowed emissions are divided into assigned amount units (AAUs).
Emissions trading, as set out in Article 17 of the Kyoto Protocol, allows countries that have emission units to spare - emissions permitted them but not "used" - to sell this excess capacity to countries that are over their targets.
Thus, a new commodity was created in the form of emission reductions or removals. Since carbon dioxide is the principal greenhouse gas, people speak simply of trading in carbon. Carbon is now tracked and traded like any other commodity. This is known as the "carbon market."

Grit chamber is a long narrow or circular tank in the primary sewage treatment plant that is designed to reduce the velocity of the flow of sewage to eliminate the girt materials such as sand, ash and clinkers, eggshells, bone chips and any inert material inorganic in nature. Grit chamber is mainly of three types: (1) Velocity controlled V-shaped long grit channels. (2) Square shaped chambers with entry and exit on opposite sides and mild hopper. (3) Vortex type cone and the centrifugal action plummets the grit to the bottom.
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.
A rotating biological contactor or RBC is a biological fixed-film treatment process used in the secondary treatment of wastewater following primary treatment. The primary treatment process involves removal of grit, sand and coarse suspended material through a screening process, followed by settling of suspended solids. The RBC process allows the wastewater to meet a biological film to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the wastewater. Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes place.
The internal circulation reactor (IC reactor) is a form of anaerobic digester. It is primarily designed to treat wastewater. The IC reactor is an evolution of the UASB and EGSB digestion systems. The digester typically produces biogas with a high concentration methane (c80%). In essence the IC to improve digestion rates and gas yields. The footprint for the IC reactor is therefore typically smaller. However, it is taller due to the increased complexity of the reactor.

A floating floor is a floor that does not need to be nailed or glued to the subfloor. The term floating floor refers to the installation method but is often used synonymously with laminate flooring. Acoustic floating floors control the transmission of sounds and vibration from floor impacts to the surrounding building structure.

Float valves can be used to prevent overfilling or overflow of tanks when the liquid needs to be diverted rather than dumped in a drain.

A Metal Float is a tool with a smooth metallic plain that is applied on flattened layers of mortar and concrete during surface finishing.

Free Float refers to the amount of tune that a task can be delayed without affecting the start date of its subsequent tasks. It is calculated as the difference between the earliest possible start date of the next task and the latest possible finish date of the current task.

Ashtamudi Wetland was designated as a Ramsar site in 2002

Hazen Williams equation for any cross-section (with slope ‘S’, velocity ‘V’, Rate of flow ‘Q’, Hazen Williams coefficient ‘C’, Hydraulic radius ‘R’) in SI units, is given by:

V = 0.849 × C × R^0.63 × S^0.54

For circular cross section with internal diameter ‘D’ – hydraulic radius, R (i.e., wet area/wet perimeter) will be:

Substituting R = D/4 in the above equation, we get:

⇒ 

⇒ 

⇒ V = 0.3545 × C × D^0.63 × S^0.54

Rate of flow, Q = Area × Velocity, where area of circular cross section is πD²/4

⇒ 

⇒ 

⇒ Q = 0.2784 × C × D^2.63 × S^0.54

U - Value: is defined as the amount of heat that gets transmitted through a unit area of a material for a unit difference in temperature. The lower the U-Value of the material, the lesser the heat transfer, and better the thermal efficiency. ECBC recommends the following U-values for glazing:

1 hectare = 10,000 sqm

Maximum permissible built-up area:

• Plot area = 2.672 hectares
• Floor Area Ratio (FAR) = 2.25
• Maximum built-up area = 2.672 * 2.25 * 10,000 = 60,120 sqm

Built-up area allocated for MIG units:

• 20% of 60,120 sqm = 0.2 * 60,120 = 12,024 sqm

Maximum number of MIG apartments:

• Each MIG unit area = 72 sqm
• Maximum number of apartments = 12,024 / 72 = 167 apartments

Total number of LIG households = (0.3*10000) = 3000 units
Total number of MIG households = (0.6*10000) = 6000 units
Total number of HIG households = (0.1*10000) = 1000 units
Total volume of compacted solid waste generated by the city = (3000 * 0.1) + (6000 * 0.15) + (1000 * 0.2) = 300 + 900 + 200 = 1400 m³
Number of days to fill the low-lying land = 70,000/1400 = 50 days

Free speed, Vsf = 90km/h
Jam density, Kj = 60 veh/km
Maximum flow,

Volume rate per second = 3 × Volume of room / 3600   in m³/sec
Volume rate per second = (3 × 10 × 25 × 4)/3600 m³/sec
Volume rate per second = 0.83 m³/sec
Area = Volume rate per second/ velocity
Area = 0.83/2
Area = 0.415 m²

• Malqaf consists of large shaft rising high above the roof of a building and depends primarily on air movement by pressure differential, and on air movement by convection.
• A windcatcher, wind tower, or wind scoop is a traditional architectural element used to create cross ventilation and passive cooling in buildings using a shaft usually rising above the building.

• A bulldozer or dozer is a large, motorized machine that travels on continuous tracks or large tires and is equipped with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction or conversion work. 
• A grader, also commonly referred to as a road grader, motor grader, or simply a blade, is a form of heavy equipment with a long blade used to create a flat surface during grading. 
• Draglines are a type of large-scale excavator used for reaching extensive depths at surface mining sites, above ground excavation sites, and more. Draglines function using a tall boom arm equipped with wire-based drag and hoist ropes. These ropes work together to move an attached bucket to and from its point of application. Once in place, the dragline operator controls the bucket so it can collect and move debris by dragging it across the surface.
• A trencher is a piece of construction equipment used to dig trenches, especially for laying pipes or electrical cables, for installing drainage, or in preparation for trench warfare. Trenchers may range in size from walk-behind models to attachments for a skid loader or tractor, to very heavy tracked heavy equipment.

Volume of the given room = 3 x 3 x 3 = 27 m³
Given α₁ = 0.2, α₂ = 0.5, α₃ = 0.1
For given room, Area of walls, A₁ = 4 x 3 x 3 = 36 m²
Area of ceiling, A₂ = Area of flooring, A₃ = 9 m²
We have, Reverberation time, R T = 0.16 (V/A)
Where A = A₁α₁+ A₂α₂+ …. + A_mα_m
A = (36 x 0.2) + (9 x 0.5) + (9 x 0.1) = 12.6
=> RT = 0.16 x (27/12.6) = 0.16 x 2.14
So, the Reverberation time of room is 0.34Sec
