Hero MotoCorp Production Operator Interview Questions, Process, and Tips

Bernoulli's theorem states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

• Bernoulli's theorem is based on the principle of conservation of energy in fluid flow.

• It states that in a steady flow of an incompressible and non-viscous fluid, the total energy remains constant along a streamline.

• The theorem relates the pressure, velocity,...read more

Mechanical energy is the energy possessed by an object due to its motion or position, while electrical energy is the energy carried by electric currents.

• Mechanical energy is related to the movement or position of an object, while electrical energy is related to the flow of electric charge.

• Mechanical energy can be kinetic (energy of motion) or potential (energy of position), while electrical energy is the movement of el...read more

The coefficient of friction is a measure of the resistance to motion between two surfaces in contact.

• The coefficient of friction is a dimensionless value that represents the ratio of the force of friction between two bodies to the force pressing them together.

• It can be static (when the objects are not moving relative to each other) or kinetic (when they are in motion).

• For example, rubber on concrete has a higher coeffi

Gravitational force increases as we go below the earth's surface.

• Gravitational force is directly proportional to the mass of an object and inversely proportional to the square of the distance between the centers of the objects.

• As we move closer to the center of the Earth, the distance between the center of the Earth and the object decreases, leading to an increase in gravitational force.

• For example, a person standing o...read more

Pressure is the amount of force applied over a specific area, while force is a push or pull on an object.

• Pressure is a scalar quantity, while force is a vector quantity.

• Pressure is measured in units such as Pascals (Pa) or pounds per square inch (psi), while force is measured in units such as Newtons (N) or pounds (lbs).

• Pressure can be distributed over a surface, while force is a single point application.

• Example: Press...read more
