Q2. What is distillation and type of distillation
Distillation is a process of separating components of a liquid mixture based on differences in boiling points.
Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.
The condensed liquid is collected separately, resulting in the separation of components based on their boiling points.
Types of distillation include simple distillation, fractional distillation, and steam distillation.
Simple distillation is used f...read more
Q3. What is Reactor types of.Reactor and use
Reactors are vessels used to contain chemical reactions. Types include batch, continuous, and semi-batch reactors.
Batch reactors are used for small-scale production and testing.
Continuous reactors operate continuously with a steady flow of reactants and products.
Semi-batch reactors combine features of both batch and continuous reactors.
Examples include CSTR (Continuous Stirred Tank Reactor) and PFR (Plug Flow Reactor).
Q4. Heat exchanger working principal and type
Heat exchangers transfer heat between two or more fluids while keeping them separate.
Heat exchangers work on the principle of transferring heat from one fluid to another without mixing them
Types of heat exchangers include shell and tube, plate, and finned tube
Examples of heat exchangers include radiators in cars and condensers in air conditioning units
Q5. What is scrubber
A scrubber is a device used to remove pollutants from exhaust gases in industrial processes.
Scrubbers can be used to remove particulates, gases, or both from emissions.
There are different types of scrubbers such as wet scrubbers, dry scrubbers, and gas scrubbers.
Wet scrubbers use a liquid to wash pollutants out of the gas stream, while dry scrubbers use a dry reagent or slurry.
Examples of scrubbers include sulfur dioxide scrubbers used in coal-fired power plants and scrubbers...read more

Q12. Which are the instruments that you worked on and their working principle
I have worked on instruments such as oscilloscopes, multimeters, and signal generators, each with their own unique working principles.
Oscilloscope: used to display and analyze the waveform of electronic signals
Multimeter: used to measure voltage, current, and resistance in electrical circuits
Signal generator: used to generate electronic signals of various frequencies and waveforms
Q13. Which type safety precautions do you follow in process ?
I follow safety precautions such as wearing personal protective equipment, conducting regular safety inspections, and providing proper training to employees.
Wearing personal protective equipment (PPE) such as gloves, safety goggles, and helmets
Conducting regular safety inspections to identify and address potential hazards
Providing proper training to employees on safety protocols and procedures
Implementing emergency response plans in case of accidents or incidents
Q14. What is the difference between centrifugal pump and reciprocating pump?
Centrifugal pump uses rotational motion to transfer fluid, while reciprocating pump uses back-and-forth motion.
Centrifugal pump uses a rotating impeller to create a suction force and transfer fluid, while reciprocating pump uses a piston or diaphragm to create pressure and move fluid.
Centrifugal pump is more suitable for high flow rate applications, while reciprocating pump is better for high pressure applications.
Centrifugal pump is generally more efficient and requires less...read more

Q16. What is Reynolds number? How it is use?
Reynolds number is a dimensionless quantity used in fluid mechanics to predict flow patterns in different fluid flow situations.
Reynolds number is calculated as the ratio of inertial forces to viscous forces in a fluid flow system.
It helps determine whether the flow is laminar (smooth and orderly) or turbulent (chaotic and unpredictable).
Reynolds number is used in various engineering applications such as designing pipes, aircraft wings, and propellers.
For example, a low Reyno...read more
