Electrolysis is a process of breaking down a compound using electricity. Aluminium can be prepared by electrolysis of alumina.
Electrolysis involves passing an electric current through a compound to break it down into its constituent elements.
Aluminium is prepared by electrolysis of alumina (Al2O3) dissolved in molten cryolite (Na3AlF6).
The process involves the use of carbon electrodes, which react with the oxygen relea...
I applied via Naukri.com and was interviewed in May 2021. There was 1 interview round.
I applied via Campus Placement and was interviewed before Jul 2023. There were 3 interview rounds.
1st round of interview was Aptitude test for 1 hr and topics were mostly logical analysis and quants
Topic was development of technology in India how it is going to affect
Hook's law states that the force needed to extend or compress a spring by a certain distance is proportional to that distance.
Force needed to extend or compress a spring is directly proportional to the displacement
The formula for Hook's law is F = kx, where F is the force, k is the spring constant, and x is the displacement
It is used to calculate the behavior of springs, elastic materials, and other systems under stres
Pearlite is a two-phased lamellar structure composed of alternating layers of ferrite and cementite in carbon steel.
Pearlite forms when austenite transforms during the cooling process of steel
It is a common microstructure in carbon steels
Pearlite provides strength and hardness to the steel
It is often used in engineering applications for its desirable properties
Steel is primarily composed of iron and carbon, with small amounts of other elements like manganese, phosphorus, sulfur, and silicon.
Steel is mainly made up of iron and carbon
Carbon content typically ranges from 0.2% to 2.1%
Other elements like manganese, phosphorus, sulfur, and silicon are also present in small amounts
Alloying elements like nickel, chromium, and molybdenum can be added to enhance specific properties

The Bayer process is a method for refining bauxite into alumina, which is the precursor to aluminum production.
The Bayer process involves crushing and grinding bauxite ore, then mixing it with sodium hydroxide at high temperatures to dissolve the alumina content.
The resulting solution is filtered to remove impurities, then cooled and seeded to promote the precipitation of pure alumina hydrate.
The alumina hydrate is the...
The most important dimensionless number is the Reynolds number, as it determines the flow regime of a fluid and is crucial in fluid dynamics.
Reynolds number is used to predict flow patterns in different fluid flow situations
It is defined as the ratio of inertial forces to viscous forces in a fluid flow
Reynolds number helps in determining whether the flow is laminar, turbulent, or transitional
It is widely used in engine...
The equation that correlates HT and fluid flow is the Darcy-Weisbach equation.
The Darcy-Weisbach equation relates the head loss due to friction in a pipe to the velocity and diameter of the pipe, as well as the friction factor.
It is commonly used in fluid mechanics and hydraulic engineering to calculate pressure drop in pipes.
The equation is expressed as: hL = f * (L/D) * (V^2/2g), where hL is the head loss, f is the f...
Systems in thermodynamics refer to the specific region of space or a quantity of matter under study.
A system can be open, closed, or isolated based on the exchange of matter and energy with its surroundings.
Examples of systems include a gas in a container, a piston-cylinder assembly, or a steam turbine.
Thermodynamic properties such as temperature, pressure, and volume are used to describe the state of a system.
The firs...
Dry steam has low moisture content and high temperature, while wet steam has high moisture content and lower temperature.
Dry steam is produced when water is heated to its boiling point and vaporizes without any liquid water droplets present.
Wet steam contains water droplets suspended in the steam, resulting in a lower temperature compared to dry steam.
Dry steam is commonly used in steam turbines for power generation, w...
I applied via Referral and was interviewed before Mar 2023. There was 1 interview round.
PTP process stands for Procure-to-Pay process, which involves the steps from purchasing goods/services to making payment.
PTP process starts with requisitioning of goods/services by a department.
Next step involves obtaining quotes, selecting a vendor, and creating a purchase order.
Goods/services are received, and invoices are matched with the purchase order.
Payment is made to the vendor based on the invoice.
The process ...

Pellet plant is a facility that transforms raw materials into pellets through a series of processes like grinding, drying, and compressing.
Raw materials such as wood chips or sawdust are fed into the plant
The raw materials are ground into a fine powder
The powder is then dried to remove moisture
The dried powder is compressed into pellets using a pellet press
The pellets are cooled and screened to ensure quality
The final ...
Replacing cooler car plates involves removing old plates, cleaning the area, and installing new plates securely.
Remove old cooler car plates carefully to avoid damaging surrounding components
Clean the area thoroughly before installing new plates to ensure proper adhesion
Securely install new cooler car plates to prevent any leaks or malfunctions
The reverse process of kiln girth gear involves disassembling, inspecting, repairing, and reassembling the gear to ensure proper functioning.
Disassemble the girth gear carefully to inspect for any damage or wear
Repair or replace any worn or damaged components
Reassemble the gear ensuring proper alignment and torque specifications
Perform testing to ensure the gear functions correctly after reassembly
