Q3. Device that converts mechanical energy into electrical energy.
Ans. 
A device that converts mechanical energy into electrical energy is called a generator.
• Generators are commonly used in power plants to convert mechanical energy from turbines into electrical energy.

• Examples include wind turbines, hydroelectric dams, and gas-powered generators.

• Generators work on the principle of electromagnetic induction, where a conductor moving through a magnetic field generates an electric current.

Q5. Types of valves and it's functioning.
Ans. 
Valves are devices used to control the flow of fluids in a system. They can be classified into different types based on their design and function.
• Gate valves: used to fully open or close the flow of fluid

• Ball valves: uses a rotating ball to control flow

• Butterfly valves: uses a disc to control flow

• Check valves: allows flow in one direction only

• Pressure relief valves: opens to release excess pressure

• Globe valves: used fo...read more

Q1. Role of a bearing in motor's poor power factor
Ans. 
Bearings in motors can cause poor power factor due to friction and inefficiency.
• Friction in bearings can lead to increased energy consumption and lower power factor.

• Worn out bearings can cause misalignment and imbalance in the motor, affecting power factor.

• Improper lubrication of bearings can increase friction and reduce efficiency, impacting power factor.

• Examples: A motor with worn out bearings may have a power factor...read more

SIMPLE AND BASIC APTITUDE TEST

Q1. WHAT IS BERNOULLI THEOREM? WHAT IS PASCAL LAW? WHAT IS PERT AND CPM ?
Ans. 
Bernoulli's theorem relates the pressure, velocity, and elevation of a fluid in a steady flow. Pascal's law states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid.
• Bernoulli's theorem states that in a steady flow of an incompressible, frictionless fluid, the sum of pressure energy, kinetic energy, and potential energy per unit volume remains constant.

• Pascal...read more
