A gate valve is typically used after NRV in pump discharge line.
Gate valve is commonly used for isolation and throttling applications
It provides a tight seal when closed
Gate valves are not suitable for regulating flow like globe valves
Examples of gate valve manufacturers include Velan, Powell, and Cameron
Eccentric reducers are used in pump suction to prevent air pockets and cavitation.
Eccentric reducers ensure smooth flow of fluid into the pump without creating air pockets
Prevents cavitation by maintaining a consistent flow velocity
Helps in reducing turbulence and pressure drop in the suction line
Electricity is the flow of electric charge, primarily through conductors, enabling energy transfer for various applications.
Electricity is generated through various sources like fossil fuels, nuclear, and renewable energy (solar, wind).
It can be classified into two types: direct current (DC) and alternating current (AC).

State updrilling refers to the process of lifting state from child components to parent components in React for better management.
State updrilling is often necessary when multiple child components need to share or access the same state.
For example, if a parent component has a list of items and a child component needs to modify that list, the state should be lifted to the parent.
This can be achieved by passing stat...

- Q1. Explain Basics OOP Pillars
- Q2. What's copy constructor. Why it's passed by reference Why copy constructor can not be void
- Ans.
A copy constructor is a special constructor that creates a new object by copying the values of another object.
Copy constructor is used to create a new object with the same values as an existing object.
It is passed by reference to avoid unnecessary object copying, which can be expensive.
Copy constructor cannot be void because it needs to return the newly created object.
- Q3. Difference in array and linked list
- Q4. Given three points how to check if they are colinear
- Ans.
To check if three points are colinear, calculate the slope between each pair of points and compare them.
Calculate the slope between the first two points using the formula: slope = (y2 - y1) / (x2 - x1)
Calculate the slope between the second and third points using the same formula
If the slopes between all pairs of points are equal, then the points are colinear
- Q5. Given point and circle how to find if point is inside circle or outside circle
- Ans.
To determine if a point is inside or outside a circle, calculate the distance between the point and the center of the circle.
Calculate the distance between the point and the center of the circle using the distance formula: sqrt((x2 - x1)^2 + (y2 - y1)^2)
If the distance is less than the radius of the circle, the point is inside the circle. If it is equal to the radius, the point is on the circle. Otherwise, it is outsid...
- Q6. How to find resultant of two vectors in terms of magnitude and direction
- Ans.
The resultant of two vectors can be found by adding the magnitudes and finding the direction using trigonometry.
To find the magnitude of the resultant, use the Pythagorean theorem: magnitude = sqrt(a^2 + b^2)
To find the direction of the resultant, use trigonometry: direction = atan(b/a)
If the vectors are given in terms of their components, add the corresponding components to find the resultant
- Q7. Can child class point points to base class?
- Ans.
Yes, a child class can point to a base class.
In object-oriented programming, a child class can inherit from a base class and use its methods and properties.
A child class can also override the methods of the base class to provide its own implementation.
Polymorphism allows a child class object to be treated as a base class object, enabling it to point to the base class.
This is useful for code reusability and creating a h...

- Q1. Working principle of induction motor
- Ans.
Induction motors work on the principle of electromagnetic induction to generate rotating magnetic fields.
Induction motors have a stator with a set of windings that are connected to an AC power source.
When the AC power is applied, it creates a rotating magnetic field in the stator.
This rotating magnetic field induces currents in the rotor bars, causing it to rotate.
The rotor never catches up to the speed of the rotating...
- Q2. What is illumination?
- Ans.
Illumination refers to the amount of light present in a space, measured in lux or foot-candles.
Illumination is crucial for visibility and safety in indoor and outdoor environments.
It is measured using units such as lux or foot-candles.
Proper illumination levels are important in workplaces, homes, and public spaces.
Examples of illumination sources include natural light, light fixtures, and streetlights.

I appeared for an interview in Sep 2024, where I was asked the following questions.
- Q1. Ask query on project
- Q2. What is python
- Q3. Syntax of dictionary in Python
- Ans.
A dictionary in Python is a mutable, unordered collection of key-value pairs, defined using curly braces.
Dictionaries are defined using curly braces: {}.
Key-value pairs are separated by a colon (:). Example: {'key': 'value'}.
Keys must be unique and immutable (e.g., strings, numbers, tuples).
Values can be of any data type, including lists and other dictionaries.
Access values using keys: my_dict['key'].
