Atotech Development Engineer Interview Questions and Answers for Freshers

Mass transfer is the movement of substances from one place to another.

• Mass transfer involves the movement of components in a system due to differences in concentration, pressure, or temperature.

• Examples include the diffusion of gases in air, the separation of components in distillation processes, and the absorption of gases in liquids.

• Mass transfer is important in various industries such as chemical engineering, food p

Distillation is a process of separating components of a liquid mixture based on differences in boiling points.

• Distillation involves heating the liquid 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.

• Common examples of distilla...read more

Types of pumps include centrifugal, reciprocating, and rotary pumps. Troubleshooting involves checking for leaks, low flow rates, and abnormal noises.

• Centrifugal pumps use rotating impellers to create flow.

• Reciprocating pumps use a piston or diaphragm to create flow.

• Rotary pumps use rotating mechanisms to create flow.

• Troubleshooting involves checking for leaks in the pump system.

• Troubleshooting involves checking for lo...read more
