  • Q2. For loop in python
  • Ans. 

    For loop in Python is used to iterate over a sequence of elements.

    • Syntax: for variable in sequence:

    • Example: for i in range(5): print(i)

    • Can be used with lists, tuples, strings, dictionaries, etc.

    • Can use break and continue statements to control loop flow

  • Q1. Tell me about your self
  • Q2. What is Azeotropic distillation
  • Ans. 

    Azeotropic distillation is a process used to separate azeotropes, which are mixtures of liquids that boil at a constant temperature.

    • Azeotropic distillation involves adding a third component to the mixture to break the azeotrope.

    • The third component forms a new azeotrope with one of the original components, which can then be separated from the other component.

    • This process is commonly used in the production of ethanol, wh...

  • Q3. Final year project
  • Q4. What is Reynolds number and range
  • Ans. 

    Reynolds number is a dimensionless quantity used to predict fluid flow patterns and turbulence.

    • Reynolds number is calculated as the ratio of inertial forces to viscous forces in a fluid.

    • It is used to determine whether a fluid flow is laminar or turbulent.

    • The range of Reynolds number for laminar flow is less than 2300, while for turbulent flow it is greater than 4000.

    • In between these values, the flow may be transitional...

Interview Questionnaire 

2 Questions

  • Q1. What is Distillation
  • Ans. 

    Distillation is a process of separating components of a liquid mixture based on their different boiling points.

    • Distillation involves heating a liquid mixture to vaporize the more volatile components.

    • The vapor is then cooled and condensed back into a liquid, separating it from the less volatile components.

    • The separated components can have different boiling points, allowing for purification or concentration of specific s...

  • Q2. What is Heat transfer
  • Ans. 

    Heat transfer is the process of energy transfer between objects or substances due to temperature differences.

    • Heat transfer can occur through conduction, convection, and radiation.

    • Conduction is the transfer of heat through direct contact between objects or substances.

    • Convection is the transfer of heat through the movement of fluids or gases.

    • Radiation is the transfer of heat through electromagnetic waves.
