Cipla Production Engineer Interview Questions and Answers

Distillation is a process of separating components of a liquid mixture based on their different boiling points.

• Distillation involves heating a liquid mixture to vaporize the more volatile components.

• The vapor is then cooled and condensed back into a liquid, separating it from the less volatile components.

• The separated components can have different boiling points, allowing for purification or concentration of specific s...read more

Heat transfer is the process of energy transfer between objects or substances due to temperature differences.

• Heat transfer can occur through conduction, convection, and radiation.

• Conduction is the transfer of heat through direct contact between objects or substances.

• Convection is the transfer of heat through the movement of fluids or gases.

• Radiation is the transfer of heat through electromagnetic waves.

• Examples of heat...read more

Azeotropic distillation is a process used to separate azeotropes, which are mixtures of liquids that boil at a constant temperature.

• Azeotropic distillation involves adding a third component to the mixture to break the azeotrope.

• The third component forms a new azeotrope with one of the original components, which can then be separated from the other component.

• This process is commonly used in the production of ethanol, wh...read more

Reynolds number is a dimensionless quantity used to predict fluid flow patterns and turbulence.

• Reynolds number is calculated as the ratio of inertial forces to viscous forces in a fluid.

• It is used to determine whether a fluid flow is laminar or turbulent.

• The range of Reynolds number for laminar flow is less than 2300, while for turbulent flow it is greater than 4000.

• In between these values, the flow may be transitional...read more
