Cohance Lifesciences Assistant Product Manager Interview Questions and Answers

Heat transfer is the movement of heat from one place to another due to a temperature difference.

• Three types of heat transfer: conduction, convection, radiation

• Conduction is the transfer of heat through a material without any movement of the material itself

• Convection is the transfer of heat through the movement of fluids (liquids or gases)

• Radiation is the transfer of heat through electromagnetic waves

• Examples: Conductio...read more

Distillation is a process used to separate components of a liquid mixture based on differences in boiling points.

• Distillation involves heating the mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

• Types of distillation include s...read more

There are various types of heat exchangers including shell and tube, plate, and finned tube.

• Shell and tube heat exchangers are commonly used in industrial applications due to their high heat transfer efficiency.

• Plate heat exchangers are compact and efficient, often used in HVAC systems and refrigeration.

• Finned tube heat exchangers are used when space is limited and increased surface area is needed for heat transfer.

• Oth...read more
