Lupin Junior Engineer Interview Questions and Answers

Laminar flow is smooth and orderly, while turbulent flow is chaotic and unpredictable.

• Laminar flow occurs at low velocities and is characterized by parallel layers of fluid moving in the same direction.

• Turbulent flow occurs at high velocities and is characterized by irregular fluctuations and mixing of fluid particles.

• Laminar flow is more energy-efficient and less noisy compared to turbulent flow.

• Examples: Laminar flow...read more

Generators work by converting mechanical energy into electrical energy through electromagnetic induction.

• Generators have a coil of wire that rotates within a magnetic field

• The rotation of the coil induces a current in the wire

• This current is then collected and transferred as electrical energy

• Examples include hydroelectric generators, wind turbines, and diesel generators
