I applied via Job Fair and was interviewed in Mar 2022. There was 1 interview round.
pH is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14.
pH stands for 'potential of hydrogen'
It is a logarithmic scale that measures the concentration of hydrogen ions in a solution
A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline
Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9
Partial pressure is the pressure exerted by a single gas in a mixture of gases.
Partial pressure is proportional to the mole fraction of the gas in the mixture.
It is calculated by multiplying the total pressure of the mixture by the mole fraction of the gas.
Each gas in a mixture contributes to the total pressure independently.
Dalton's law of partial pressures states that the total pressure of a gas mixture is equal to t...
Ideal gas law is a fundamental law of physics that describes the behavior of gases under varying conditions.
It relates the pressure, volume, temperature, and number of particles of a gas.
The law is expressed as PV = nRT, where P is pressure, V is volume, n is the number of particles, R is the gas constant, and T is temperature.
The law assumes that the gas particles are in constant random motion and that there are no in...
Work and energy are fundamental concepts in physics. As a chemical engineer, I will apply these concepts to optimize processes, improve efficiency, and develop sustainable solutions.
Work refers to the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.
Energy is the capacity to do work and exists in various forms such as kinetic, potential, thermal, chemical, a...
The unit of pressure is Pascal (Pa) and the unit of force is Newton (N).
Flow measuring devices include orifice plates, venturi tubes, and flow nozzles.
Pressure is measured in units of force per unit area.
Force is a vector quantity that can be measured using a force gauge or load cell.
In fluid mechanics, pressure is often used to calculate flow rate.
Examples of flow measuring devices include rotameters, magnetic flow me

Laws governing energy and its transformations in physical systems.
First law: Energy cannot be created or destroyed, only transferred or converted.
Second law: Entropy of a closed system always increases over time.
Third law: Absolute zero cannot be reached.
Applications in engineering, physics, and chemistry.
Examples: heat engines, refrigeration, combustion, chemical reactions.
Steam ejectors are devices that use steam to create a vacuum by entraining and compressing gases or vapors.
Steam ejectors work by using a high-pressure steam jet to create a low-pressure zone, which draws in gases or vapors from the surrounding area.
The entrained gases or vapors are then compressed and discharged through a diffuser, which increases their velocity and reduces their pressure.
Steam ejectors are commonly u...
Heat pump is a device that transfers heat from a lower temperature to a higher temperature.
Heat pump works on the principle of refrigeration cycle.
It consists of four main components: evaporator, compressor, condenser, and expansion valve.
The refrigerant absorbs heat from the low-temperature source (air, water, or ground) in the evaporator and gets converted into a gas.
The compressor then compresses the gas, which incr...
Grinding is a process of removing material from a workpiece using an abrasive wheel or belt.
Grinding is used to achieve high dimensional accuracy and surface finish.
It is commonly used in manufacturing industries for finishing operations.
Different types of grinding machines are used for different applications such as cylindrical, surface, and centerless grinding.
Grinding can be done manually or with the help of compute...

Types of pumps include centrifugal, positive displacement, and axial flow pumps. Each has a unique characteristic curve.
Centrifugal pumps are commonly used in industrial applications and have a steep characteristic curve.
Positive displacement pumps are used for high viscosity fluids and have a nearly constant flow rate.
Axial flow pumps are used for low head, high flow rate applications and have a flat characteristic cu...
Distillation is a process of separating components of a mixture based on their boiling points. McCabe Thiele method is a graphical method used for designing distillation columns.
Distillation is used in various industries such as petroleum, chemical, and food processing.
There are two main types of distillation: batch distillation and continuous distillation.
McCabe Thiele method is used to determine the number of theoret...

Modes of heat transfer include conduction, convection, and radiation.
Conduction: Heat transfer through direct contact between particles or objects.
Convection: Heat transfer through the movement of fluids or gases.
Radiation: Heat transfer through electromagnetic waves.
Examples: Cooking on a stove (conduction), heating a room with a radiator (convection), feeling the warmth of the sun (radiation).
