- Q1. What is oops concepts?
- Ans.
Object-oriented programming concepts that focus on classes and objects.
Encapsulation: Bundling data and methods that operate on the data into a single unit (class).
Inheritance: Ability of a class to inherit properties and behavior from another class.
Polymorphism: Ability to present the same interface for different data types.
Abstraction: Hiding the complex implementation details and showing only the necessary features.

- Q1. What are principles of testing?
- Ans.
Principles of testing are guidelines that help in designing effective test cases and ensuring thorough testing of software.
Testing shows the presence of defects, not their absence.
Exhaustive testing is impossible, so testing efforts should be focused on high-risk areas.
Early testing saves time and cost in the long run.
Defect clustering suggests that a small number of modules contain the majority of defects.

- Q2. How many points need inspection
- Ans.
The number of points that need inspection varies depending on the specific context and requirements.
The number of points needing inspection can be determined by the scope of the analysis or evaluation.
Factors such as the size of the dataset, complexity of the data, and specific objectives of the analysis can influence the number of points to inspect.
For example, in a quality control process, a certain percentage of pro...
- Q3. Is tml important for maintenance
- Ans.
Yes, Total Maintenance Loss (TML) is important for maintenance as it helps in identifying critical equipment and prioritizing maintenance activities.
TML is a key performance indicator used to measure the overall maintenance effectiveness of a system or equipment.
It helps in identifying equipment that is causing the most downtime or losses in production.
By analyzing TML, maintenance teams can prioritize their efforts on...

- Q1. How to design the diameter of distillation column
- Ans.
The diameter of a distillation column is designed based on factors such as feed flow rate, composition, pressure, and efficiency.
Calculate the required vapor and liquid flow rates based on the feed composition and desired separation efficiency.
Consider the pressure drop along the column and the desired residence time for the vapor and liquid phases.
Use design equations and correlations to determine the optimal diameter...
- Q2. How to calculate no of trays and reflux ratio?
- Ans.
Number of trays and reflux ratio can be calculated using various methods such as McCabe-Thiele method or Fenske equation.
Use McCabe-Thiele method for distillation columns to determine number of trays required.
Calculate reflux ratio by dividing the liquid returning to the column by the liquid leaving the top tray.
Consider factors such as desired separation efficiency and operating conditions when determining number of t
- Q3. Tray vs packing?
- Ans.

- Q4. How to calculate p drop in a pipe
- Ans.
To calculate pressure drop in a pipe, use the Darcy-Weisbach equation or the Hazen-Williams equation.
Use the Darcy-Weisbach equation: ΔP = f * (L/D) * (ρ * V^2) / 2
Use the Hazen-Williams equation: ΔP = 10.67 * Q^1.85 / (C^1.85 * D^4.87)
Where ΔP is the pressure drop, f is the Darcy friction factor, L is the pipe length, D is the pipe diameter, ρ is the fluid density, V is the fluid velocity, Q is the flow rate, and C is...
- Q5. Explain le chatelier principle
- Ans.
Le Chatelier's principle states that a system at equilibrium will respond to a stress by shifting to counteract the stress and restore equilibrium.
If a stress is applied to a system at equilibrium, the system will adjust to minimize the effect of the stress.
Changes in concentration, pressure, or temperature can cause a shift in equilibrium.
For example, if more reactants are added to a system at equilibrium, the system ...
