INOX Air Products Interview Questions, Process, and Tips

Q1. What is Ovality allowed in piping
Ans. 
Ovality allowed in piping refers to the maximum allowable deviation from a perfect circle shape in the pipe.
• Ovality is typically expressed as a percentage of the pipe's diameter.

• The standard ovality allowed in piping is usually around 1% to 3%.

• Excessive ovality can lead to issues such as leaks, pressure drops, and flow restrictions.

• Ovality can be measured using tools like calipers or laser measurement devices.

Q1. What is Bernoulli equation and its significance
Ans. 
The Bernoulli equation relates the pressure, velocity, and elevation of a fluid flow.
• Describes the conservation of energy in a flowing fluid

• States that the sum of pressure energy, kinetic energy, and potential energy per unit volume remains constant along a streamline

• Used in fluid mechanics to analyze fluid flow in pipes, nozzles, and wings

Q2. What is pascals law?
Ans. 
Pascal's law states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.
• Pressure applied to a confined fluid is transmitted equally in all directions

• The pressure at any point in a fluid at rest is the same in all directions

• Used in hydraulic systems to generate force or motion

• Example: Hydraulic car brakes work based on Pascal's

Q3. How gravity affect the things and what it is?
Ans. 
Gravity is a force that pulls objects towards each other. It affects the weight of objects and determines how they move on Earth.
• Gravity is a fundamental force of nature that causes objects with mass to be attracted to each other.

• The strength of gravity depends on the mass of the objects and the distance between them.

• Gravity affects the weight of objects by pulling them towards the center of the Earth.

• Gravity also dete...read more
