Distillation is a process of separating components of a liquid mixture based on differences in boiling points.
Boiling the liquid mixture to create vapor
Collecting and condensing the vapor back into liquid form
Separating the components based on their different boiling points
Examples: Distilling alcohol to make spirits, purifying water through distillation
The t-x-y curve is a graph that shows the relationship between temperature (t), composition (x), and phase equilibrium (y) in a system.
The t-x-y curve is commonly used in chemical engineering to analyze phase behavior in systems with multiple components.
It shows how the temperature affects the composition of the phases present in the system at equilibrium.
The curve typically consists of two lines representing the compo...
Volatility refers to the degree of variation of a trading price series over time.
Volatility measures the rate at which the price of a security increases or decreases.
High volatility indicates large price swings, while low volatility indicates smaller price movements.
Examples of volatile assets include cryptocurrencies and certain stocks.
The term 'q' can refer to various things depending on the context, such as a variable in mathematics or physics, a quality factor in engineering, or a question in general.
In mathematics, 'q' is often used as a variable in equations, such as in algebra or calculus.
In physics, 'q' can represent charge, heat, or momentum, depending on the specific equation or context.
In engineering, 'q' may refer to the quality factor of ...
A heat exchanger is a device used to transfer heat between two or more fluids.
Heat exchangers can be classified based on their construction (e.g. shell and tube, plate, finned tube)
They work on the principle of heat transfer through conduction, convection, or radiation
Common applications include HVAC systems, refrigeration units, and industrial processes

I applied via campus placement at Indian School of Mines (ISM), Dhanbad
RTD and thermocouple are types of temperature sensors used in various industries.
RTD stands for Resistance Temperature Detector and uses the principle of change in electrical resistance with temperature to measure temperature.
Thermocouple uses the principle of Seebeck effect where a voltage is generated when two dissimilar metals are joined at two junctions and exposed to different temperatures.
RTD is more accurate and...
I was interviewed in Apr 2017.
Crude oil is separated from water through a process called oil-water separation.
Oil-water separation is achieved by using various techniques such as gravity separation, centrifugation, and filtration.
Gravity separation involves allowing the mixture of crude oil and water to settle, with the oil rising to the top due to its lower density.
Centrifugation utilizes the centrifugal force to separate the oil and water by spin...

I applied via Approached by Company and was interviewed before Apr 2023. There was 1 interview round.
Refrigeration cycle is a process in which a refrigerant absorbs heat from a low-temperature space and releases it in a high-temperature space.
Refrigerant absorbs heat from the low-temperature space (evaporator)
Refrigerant is compressed to increase its temperature and pressure
High-temperature refrigerant releases heat in the condenser
Refrigerant expands in the expansion valve to lower its temperature and pressure
Cycle r...
Different types of fit in GD&T include clearance fit, interference fit, and transition fit.
Clearance fit: Parts are intended to have a gap between them for easy assembly and disassembly.
Interference fit: Parts are intended to be pressed or hammered together for a tight fit.
Transition fit: Parts have a combination of clearance and interference fit depending on the specific requirements.
Examples: A clearance fit is used ...
Material properties refer to the characteristics and behaviors of materials under specific conditions.
Material properties include mechanical, thermal, electrical, and optical properties.
Examples of material properties are strength, conductivity, melting point, and refractive index.
Understanding material properties is crucial for designing and selecting materials for specific applications.
I was interviewed in Apr 2017.
I was interviewed in Mar 2023.
