10+ Interview Questions and Answers

A centrifugal pump is a mechanical device used to transport fluids by converting rotational kinetic energy to hydrodynamic energy.

• Centrifugal pumps are commonly used in industries such as oil and gas, chemical, and water treatment.

• They work by using an impeller to create a low-pressure area at the center of the pump, which draws in fluid and then expels it at high pressure through the outlet.

• Pumps are used to transport fluids, while compressors are used to compress gases.

NPSH stands for Net Positive Suction Head. It is a measure of the pressure available at the suction side of a pump to prevent cavitation.

• NPSH is important in pump selection and operation.

• It is the difference between the total suction head and the vapor pressure of the pumped fluid.

• Insufficient NPSH can lead to cavitation, which can damage the pump and reduce its efficiency.

• Different types of pumps have different NPSH requirements.

• Examples of pump types include centrifugal pum...read more

• Take into account the type of fluid being pumped and its compatibility with the pump materials.

• Consider the system requirements, such as space limitations or specific industry standards.

• Examples: Centrifugal pumps...read more

A distillation column is a unit used in chemical processes to separate mixtures into their individual components based on their boiling points.

• Distillation column works on the principle of vapor-liquid equilibrium.

• It consists of a vertical column with multiple trays or packing material.

• A mixture is fed into the column and heated to generate vapor.

• The vapor rises through the column and comes into contact with the liquid on the trays or packing.

• Components with lower boiling poi...read more

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• Compressors work by using a piston or a rotating impeller to decrease the volume of a gas.

• As the volume decreases, the pressure of the gas increases.

• Compressors are commonly used in refrigeration systems, air conditioning units, and industrial processes.

• Examples of compressors include reciprocating compressors, rotary screw compressors, and centrifugal compressors.

Equipment design involves identifying user needs, creating prototypes, testing, and refining the design.

• Refine the design based on feedback and testing

• Consider safety, ergonomics, and usability

• Use appropriate materials and manufacturing processes

• Ensure compliance with relevant regulations and standards

Managing risk and changes in a project involves proactive planning, communication, and flexibility.

• Identify potential risks early on and create a risk management plan

• Regularly communicate with stakeholders to address any changes or issues

• Be flexible and adapt to changes in scope, timeline, or resources

• Utilize project management tools to track and monitor risks and changes

• Prioritize risks based on impact and likelihood to occur

ICH Guidelines are a set of standards for the design, conduct, performance, monitoring, auditing, recording, analysis, and reporting of clinical trials.

• ICH Guidelines are developed by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH)

• They aim to ensure the safety, quality, and efficacy of pharmaceutical products

• Examples of ICH Guidelines include E6 for Good Clinical Practice and E9 for Statistical Principles for Clini...read more

Unit operations involved in cooking include mixing, heating, cooling, and separation processes.
