Q1. Laminar vs Turbulant Flow
Ans. 
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

Q2. Explain How Generator Works
Ans. 
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

Q2. What is a machine? Principal of machine? Adwantage of high voltage?
Ans. 
A machine is a device that uses energy to perform a task. The principle of a machine is to make work easier. High voltage has advantages in power transmission.
• A machine is a mechanical or electrical device that uses energy to perform a task.

• The principle of a machine is to make work easier by multiplying force or changing the direction of force.

• Examples of machines include engines, motors, pumps, and generators.

Q3. What is skin effect?
Ans. 
Skin effect is the tendency of high-frequency alternating current to flow near the surface of a conductor.
• Skin effect occurs due to the self-inductance of the conductor.

• It increases with frequency and decreases with the diameter of the conductor.

• It can cause power loss and distortion in high-frequency applications.

• It is mitigated by using stranded conductors or hollow conductors.

• Example: Skin effect is a major concern ...read more
