10+ JSW Steel Interview Questions and Answers

There are three modes of heat transfer: conduction, convection, and radiation.

• Conduction is the transfer of heat through a material without any movement of the material itself.

• Convection is the transfer of heat through a fluid (liquid or gas) due to the movement of the fluid.

• Radiation is the transfer of heat through electromagnetic waves.

• Performance curve of a pump shows the relationship between the flow rate and head (pressure) generated by the pump.

• Priming is the process of...read more

Thermodynamics deals with energy transfer in a system while heat transfer operations focus on the transfer of heat from one body to another.

• Thermodynamics is concerned with the study of energy and its transformation from one form to another.

• Heat transfer operations deal with the transfer of heat from one body to another.

• Thermodynamics is a theoretical concept while heat transfer operations are practical applications of thermodynamics.

• Thermodynamics involves the study of therm...read more

Control valve parts are components of a control valve that help regulate the flow of fluids or gases in a system.

• Valve body

• Actuator

• Valve trim (plug, seat, stem)

• Bonnet

• Packing

• Positioner

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 is required.

• Gate valves are often used in water treatment ...read more

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 voltage of 12 volts and a resistance of 4 ohms, the current f...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.
