A cooling tower is a heat rejection device that removes waste heat to the atmosphere through the cooling of a water stream.
Cooling towers are used in industrial processes to cool water or other fluids by evaporating a small portion of the water.
They are commonly used in power plants, refineries, petrochemical plants, and HVAC systems.
Cooling towers can be classified into two main types: natural draft and mechanical dra...
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
Compressors are commonly used in refrigeration, air conditioning, and gas turbines.
They work by taking in a gas at a low pressure and volume, and then compressing it to a higher pressure and lower volume.
There are different types of compressors, such as reciprocating, rotary, and centrifugal compressors.

Alumina is obtained from bauxite through the Bayer process.
Bauxite is crushed and mixed with sodium hydroxide to form a slurry.
The slurry is heated and pressurized in a digester to dissolve the alumina content.
The resulting solution is cooled and filtered to remove impurities.
The purified solution is then heated to precipitate the alumina as a white powder.
The alumina powder is washed, dried, and calcined to produce pu...
The reaction for Al extraction from alumina involves the reduction of alumina using carbon or electrolysis.
Alumina (Al2O3) is first converted into aluminum chloride (AlCl3) by reacting with hydrochloric acid.
The aluminum chloride is then reduced to aluminum metal by either carbon reduction or electrolysis.
In carbon reduction, carbon (usually in the form of coke) is heated with the aluminum chloride to produce aluminum ...
There are four main types of cast iron: gray iron, white iron, ductile iron, and malleable iron.
Gray iron is the most common type and has excellent castability and good machinability.
White iron is very hard and brittle, often used for wear-resistant applications.
Ductile iron has high strength and ductility, making it suitable for a wide range of applications.
Malleable iron is heat-treated to improve its strength and du
I applied via Recruitment Consultant and was interviewed in Nov 2019. There were 3 interview rounds.
Mining is the process of extracting valuable minerals or other geological materials from the earth's surface or underground.
Mining is done to obtain various resources such as coal, gold, diamonds, and metals like iron, copper, and aluminum.
It involves the removal of soil, rocks, and other materials to access the desired minerals.
Mining can be categorized into surface mining and underground mining, depending on the loca...

The Howrah Bridge is a cantilever bridge that spans the Hooghly River in West Bengal, India.
Built in 1943, it is one of the busiest bridges in the world, carrying over 100,000 vehicles and countless pedestrians daily.
The bridge does not have any nuts or bolts and is held together by rivets.
It is a famous landmark in Kolkata and is often referred to as the 'Gateway of Kolkata'.

Final drive is a component in a vehicle's powertrain system that delivers power from the transmission to the wheels.
Final drive is typically found in rear-wheel drive and four-wheel drive vehicles.
It consists of a differential and a set of gears that transfer power to the wheels.
Final drive ratio determines the speed and torque output of the vehicle.
Examples include rear axle final drives in trucks and SUVs.
Differential is a mathematical concept that represents the rate of change of a function with respect to one of its variables.
In calculus, the differential of a function f(x) is denoted as df(x) and represents the change in f(x) for a small change in x.
Differentials are used in various fields such as physics, engineering, and economics to analyze rates of change.
For example, in physics, the differential of position with...
Gear backlash refers to the amount of clearance or play between meshing gears.
Gear backlash is important to prevent binding and ensure smooth operation of gears.
It is measured in terms of the distance between the mating teeth when they are not in contact.
Proper adjustment of gear backlash is crucial for efficient power transmission.
Examples of gear backlash adjustment include shimming or adjusting the position of the g
Bearing preload is the force applied to a bearing to remove internal clearance and improve rigidity.
Bearing preload is the force exerted on a bearing to eliminate internal clearance
It helps improve rigidity and reduce noise and vibration
Proper bearing preload ensures optimal performance and longevity of the bearing
Examples include adjusting the nut on a wheel bearing or using shims to preload a ball screw bearing
A floating seal is a type of mechanical seal used in rotating equipment to prevent leakage of fluids.
Consists of two sealing rings with one ring rotating and the other stationary
Used in applications such as pumps, mixers, and agitators
Provides better sealing performance and longer service life compared to traditional seals
Endplay of a bearing refers to the axial movement or play in the bearing along its axis.
Endplay is the amount of axial movement allowed in a bearing before it reaches its limit.
It is important to properly set the endplay in a bearing to ensure proper functioning and longevity.
Endplay can be adjusted by adding or removing shims or spacers in the bearing assembly.
Excessive endplay can lead to noise, vibration, and premat...
