Deepak Nitrite Head Human Resources Interview Questions and Answers

Reflux ratio is the ratio of the amount of reflux to the amount of distillate in a distillation column.

• Reflux ratio is an important parameter in distillation processes.

• It is defined as the ratio of the amount of liquid returned to the column as reflux to the amount of liquid removed as distillate.

• A high reflux ratio results in a higher purity of the distillate, but also requires more energy to maintain.

• Reflux ratio can...read more

R=f/d is the formula for calculating resistance.

• R is the resistance of the material

• f is the force applied to the material

• d is the distance over which the force is applied

• The formula is commonly used in physics and engineering

• Example: calculating the resistance of a wire

A loop is a programming construct that repeats a set of instructions until a specific condition is met.

• Loops are used to automate repetitive tasks.

• There are three types of loops: for, while, and do-while.

• For loop is used when the number of iterations is known.

• While loop is used when the number of iterations is unknown.

• Do-while loop is used when the loop must execute at least once.

• Example: for(int i=0; i<10; i++) { //co

F/o and F/c are aviation terms used to refer to the first officer and flight crew respectively.

• F/o stands for first officer, who is the second-in-command of the aircraft and assists the captain in flying the plane.

• F/c stands for flight crew, which includes all the members of the crew who are responsible for the safety and comfort of the passengers.

• The first officer is also known as the co-pilot and is responsible for m...read more

Distillation column is used to separate components of a mixture based on their boiling points.

• It works on the principle of vapor-liquid equilibrium.

• The mixture is heated and vaporized in the column.

• The vapor rises and condenses at different heights based on their boiling points.

• The condensed liquid is collected in trays or plates.

• The separated components are then collected from different trays.

• It is commonly used in th

• I have worked with reactors from different manufacturers such as ABC...read more

Mechanical seals are used to prevent leakage between two rotating parts in a machine. There are various types of mechanical seals.

• Types of mechanical seals include pusher, non-pusher, cartridge, and split seals.

• Parameters of mechanical seals include seal face material, seal face design, and secondary sealing elements.

• Seal face materials can be ceramic, carbon, or tungsten carbide.

• Seal face design can be single or doubl...read more

I handle various types of columns and troubleshoot issues related to them.

• I handle columns such as HPLC, GC, ion exchange, and size exclusion.

• I troubleshoot issues related to column clogging, peak broadening, and retention time shifts.

• I also perform regular maintenance and calibration to ensure optimal column performance.

• For example, if I notice a decrease in column efficiency, I may check for leaks, adjust the flow ra...read more

Vacuum systems use various types of equipment, including dry vacuum pumps.

• Vacuum systems require pumps to create and maintain a vacuum.

• Dry vacuum pumps are oil-free and use non-contacting parts to create a vacuum.

• Examples of dry vacuum pump makes include Edwards, Leybold, and Agilent.

• Other types of vacuum pumps include rotary vane, scroll, and turbomolecular pumps.
