Bharat Petroleum Apprentice Trainee Interview Questions and Answers

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Ohm's law is expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.

• It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit has a vol...read more

Water density decreases as temperature increases.

• Water density is the mass of water per unit volume.

• As temperature increases, water molecules gain energy and move faster.

• Faster moving molecules create more space between them, resulting in lower density.

• For example, ice has a higher density than liquid water because the molecules are more closely packed.

A gate valve is a type of valve that uses a gate or wedge-shaped disc to control the flow of fluid.

• Gate valves are commonly used in industrial applications to control the flow of liquids or gases.

• The gate or disc of a gate valve moves up and down to open or close the valve.

• Gate valves provide a tight seal when closed, preventing any leakage.

• They are typically used in applications where a full flow or no flow condition ...read more

• Valve body

• Actuator

• Valve trim (plug, seat, stem)

• Bonnet

• Packing

• Positioner
