Summer Trainee Interview Questions and Answers

Pumps are devices used to move fluids. Types include centrifugal, positive displacement, and axial flow pumps.

• Centrifugal pumps are used for low viscosity fluids like water and chemicals.

• Positive displacement pumps are used for high viscosity fluids like oil and slurry.

• Axial flow pumps are used for high flow, low head applications like irrigation and drainage.

• Other types include diaphragm, gear, and peristaltic pumps.

• Applications include water supply, wastewater treatment, oi...read more

AJAX is a technique for creating interactive web applications by asynchronously sending and receiving data from a server without interfering with the display and behavior of the existing page. JSON is a lightweight data interchange format.

• AJAX stands for Asynchronous JavaScript and XML

• It allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes

• JSON (JavaScript Object Notation) is a lightweight data interchange format t...read more

Yes, I am able to handle pressure. I thrive in high-pressure situations and always deliver my best work.

• I have experience working on tight deadlines and managing multiple projects simultaneously

• I remain calm and focused under pressure, allowing me to make sound decisions

• An example of handling pressure was during a project deadline where I had to work long hours to ensure its completion

NPSH stands for Net Positive Suction Head, a measure of the pressure available at the suction port of a pump.

• NPSH is important for determining if a pump will operate properly without cavitation.

• It is calculated by subtracting the vapor pressure of the liquid from the total suction head.

• NPSH is typically expressed in units of meters or feet.

• Adequate NPSH is crucial for preventing damage to the pump and ensuring efficient operation.

Distillation column is a vertical vessel used to separate components in a liquid mixture based on their boiling points.

• Design the column with trays or packing material to increase surface area for vapor-liquid contact.

• Include a reboiler at the bottom to vaporize the liquid mixture.

• Add a condenser at the top to condense the vapor back into liquid.

• Consider the number of theoretical stages required for separation efficiency.

• Choose appropriate materials of construction based on t...read more
