- Q1. What is the Transformer?
- Ans.
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are commonly used in power distribution systems to step up or step down voltage levels.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding receives electrical energy from a power source, whi...
- Q2. What is a relay? And how does it provide security?
- Ans.
A relay is an electrically operated switch that controls the flow of current in a circuit. It provides security by isolating the control circuit from the high voltage circuit.
A relay is a device that uses an electromagnet to mechanically open or close contacts in a circuit.
It acts as a switch, allowing or interrupting the flow of current in a circuit.
Relays provide security by isolating the control circuit from the hig...

(5 Questions)
- Q1. 1.Tell me about your self What Is ph . It's range
- Ans.
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
- Q2. What is partial pressure
- Ans.
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...
- Q3. What is Ideal gas law
- Ans.
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...
- Q4. What do you mean by work & energy As an chemical Engineer what you will do for this organisation
- Ans.
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...
- Q5. Flow measuring device. Unit of pressure, force,
- Ans.
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

Interview Questionnaire
7 Questions
- Q1. Types of pump, compressors?
- Ans.
Pumps: centrifugal, positive displacement, axial flow. Compressors: reciprocating, rotary, centrifugal.
Centrifugal pumps use a rotating impeller to move fluid.
Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge.
Axial flow pumps use propellers to move fluid.
Reciprocating compressors use pistons to compress gas.
Rotary compressors use rotating screws or vanes to compress ...
- Q2. Characteristic curve of pump?
- Ans.
Characteristic curve of a pump shows the relationship between flow rate and head developed by the pump.
It is a graph plotted between flow rate and head developed by the pump.
It helps in determining the efficiency of the pump.
The curve is obtained by conducting experiments on the pump.
It is used to select the appropriate pump for a given application.
- Q3. What is shutoff pressure in pump?
- Ans.
Shutoff pressure is the maximum pressure a pump can generate when it is not pumping any fluid.
Shutoff pressure is also known as deadhead pressure.
It is the pressure at which the pump can no longer move any fluid.
It is important to know the shutoff pressure to prevent damage to the pump and system.
For example, if the shutoff pressure of a pump is 100 psi, the pump will stop generating flow when the pressure in the syste
- Q4. What are the type of column and in what scenarios you would select that colum?
- Ans.
Types of columns and their selection criteria for engineering projects.
Types of columns include steel, concrete, timber, and composite columns.
Selection criteria depend on factors such as load capacity, material availability, and cost.
For example, steel columns are often used in high-rise buildings due to their strength and durability.
Concrete columns are preferred for their fire resistance and low maintenance.
Timber c...
- Q5. Design of column, design of heat exchanger, design of centrifugal pump?
- Ans.
Design of column, heat exchanger, and centrifugal pump involves various factors such as fluid properties, operating conditions, and material selection.
Column design involves determining the column diameter, height, and packing material based on the required separation efficiency and pressure drop.
Heat exchanger design involves selecting the appropriate type of exchanger, determining the heat transfer area, and selectin...
- Q6. What is joule Thomasan coefficient in cryogenic technology?
- Ans.
Joule-Thomson coefficient is the change in temperature of a gas when it is allowed to expand or contract without any work being done.
It is a measure of the rate of change of temperature with respect to pressure at constant enthalpy.
It is used in cryogenic technology to determine the cooling effect of a gas when it expands through a valve or porous plug.
The coefficient can be positive or negative depending on the gas an...
- Q7. Refrigeration cycle?
- Ans.
Refrigeration cycle is a thermodynamic process used in refrigerators and air conditioners to transfer heat from a low-temperature region to a high-temperature region.
The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
The refrigerant is compressed by the compressor and then condensed in the condenser, releasing heat to the surroundings.
The high-pressure liquid refrigerant ...
