National Organic Chemical Industries Production Graduate Engineer Trainee 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

Organic chemistry deals with carbon-based compounds while inorganic chemistry deals with non-carbon-based compounds.

• Organic chemistry involves the study of hydrocarbons, alcohols, carbohydrates, proteins, and nucleic acids.

• Inorganic chemistry involves the study of metals, minerals, and non-carbon-based compounds like water, salts, and acids.

• Organic compounds are generally covalently bonded while inorganic compounds can...read more
