Q190. Flowmeter working principle
Flowmeter measures the rate of fluid flow through a pipe or channel.
Flowmeter works on the principle of measuring the velocity of the fluid and multiplying it with the cross-sectional area of the pipe or channel.
There are different types of flowmeters such as differential pressure flowmeters, positive displacement flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc.
Flowmeters are commonly used in industries such as oil and gas, chemical, water treatment, and fo...read more

Identifies risks and weaknesses in processes
Improves processes and procedures
Enhances overall quality and efficiency
Provides assurance to stakeholders
Q192. Type of pump gerabox reactor
The type of pump gearbox reactor depends on the specific application and requirements.
The pump gearbox reactor can be a centrifugal pump, positive displacement pump, or other types depending on the application.
The gearbox can be a single-stage or multi-stage design.
The reactor can be a batch or continuous process.
Examples include chemical processing, oil refining, and power generation.
Q193. Expected CTC Relocation Condition
Expected CTC and willingness to relocate are negotiable based on the job offer and benefits.
Expected CTC can vary based on the job responsibilities, experience, and industry standards.
Relocation condition depends on the location of the job, personal circumstances, and benefits offered by the company.
Both Expected CTC and Relocation Condition are open for discussion during the interview process.
Q194. Describe heat exchanger type?
A heat exchanger is a device used to transfer heat between two or more fluids, typically to cool or heat a process.
Heat exchangers can be classified based on their construction (shell and tube, plate, finned tube, etc.)
They work by allowing heat to pass from one fluid to another without the fluids mixing.
Examples include car radiators, air conditioning units, and refrigeration systems.
Q195. Troubleshooting techniques
Troubleshooting techniques involve identifying, analyzing, and solving problems to ensure smooth operations.
Identify the problem by gathering information and understanding the symptoms.
Analyze the possible causes of the issue by using logical reasoning and deductive skills.
Develop a plan of action to address the problem systematically.
Implement the solutions and monitor the results to ensure effectiveness.
Document the troubleshooting process for future reference and continuou...read more
Q196. what type reaction is done

Please provide more information about what reaction you are referring to.
Are you asking about a chemical reaction, a biological reaction, or a reaction in a different context?
Without more information, it is impossible to provide a specific answer.
Q197. What is strong alkali
Strong alkali refers to a substance with a high pH level that can cause severe burns and irritation to skin and eyes.
Strong alkalis have a pH level above 10
They are highly corrosive and can cause severe burns on contact with skin
Examples include sodium hydroxide (caustic soda) and potassium hydroxide
Q198. Interlocks in distillation column
Q199. How to handle safety

Promote a culture of safety by encouraging reporting of safety concerns and near misses
Ensure comp...read more
Q200. Types of reactors
Types of reactors include batch reactors, continuous stirred tank reactors, plug flow reactors, and fluidized bed reactors.
Batch reactors operate in a closed system with a fixed amount of reactants.
Continuous stirred tank reactors have continuous flow of reactants and products.
Plug flow reactors have a continuous flow with no mixing of reactants along the length of the reactor.
Fluidized bed reactors use a fluid to suspend solid particles, allowing for better mixing and heat t...read more
