Tata Steel Junior Engineer Trainee Interview Questions and Answers

Q1. What is Dynamic Viscosity?
Ans. 
Dynamic viscosity is a measure of a fluid's resistance to flow under applied force.
• Dynamic viscosity is also known as absolute viscosity.

• It is a measure of how thick or thin a fluid is.

• Units of dynamic viscosity are Pascal-seconds (Pa·s) or Poise (P).

• Water has a dynamic viscosity of about 0.001 Pa·s at room temperature.

Q2. Draw the stress strain diagram.
Ans. 
The stress-strain diagram shows the relationship between stress and strain in a material.
• The stress-strain diagram typically consists of a linear elastic region, a yield point, and a plastic deformation region.

• The slope of the linear elastic region represents the material's Young's Modulus.

• The yield point indicates the stress at which the material begins to deform plastically.

• The ultimate tensile strength is the maximu...read more

In group discussion we discussed about global warming.

Q1. What is the construction and line diagram of centrifugal pump?
Ans. 
A centrifugal pump consists of an impeller, casing, and suction/discharge pipes. The line diagram shows the flow of fluid through the pump.
• Construction includes impeller, casing, suction pipe, and discharge pipe

• Impeller rotates to create centrifugal force, pushing fluid outwards

• Suction pipe brings fluid into the pump, discharge pipe sends it out

• Line diagram shows the flow path of fluid through the pump
