Duct design involves considering airflow requirements, material selection, sizing, and layout.
Determine the airflow requirements for the space or system.
Select appropriate materials based on factors like temperature, pressure, and corrosion resistance.
Calculate the duct size based on airflow velocity and pressure drop.
Design the layout considering space constraints, accessibility, and efficiency.
Consider factors like n...
Different types of pipe sizes used in air header include 1/2 inch, 3/4 inch, 1 inch, and 2 inch.
Common pipe sizes used in air headers are 1/2 inch, 3/4 inch, 1 inch, and 2 inch.
Pipe size selection depends on the required air flow rate and pressure drop.
Larger pipe sizes are used for higher flow rates and to minimize pressure drop.
Smaller pipe sizes are used for lower flow rates and when space is limited.
Pipe sizes can ...

Diaphragm valves
Solenoid valves
Piston valves
Rotary valves
Poppet valves
Inlet outlet area calculation is a process of determining the area of the inlet and outlet openings of a system.
Calculate the area of the inlet and outlet openings using appropriate formulas
Consider the shape of the openings (e.g., circular, rectangular) and use the corresponding formulas
Measure the dimensions of the openings accurately to obtain precise results
Take into account any obstructions or restrictions in the ...
A weldment in SolidWorks is a feature that allows users to create and design welded structures.
Weldments are commonly used in the design of structures such as frames, trusses, and supports.
They are created by sketching a 2D profile and then using the weldment feature to extrude it along a path.
Weldments can be made from various materials such as steel, aluminum, or wood.
They can include different types of welds, such a...
To use the same sketch in different planes with different sizes, you can create a base sketch and then use it as a reference to create new sketches.
Create a base sketch with the desired shape and size
Use the base sketch as a reference to create new sketches on different planes
Modify the dimensions and size of the new sketches as needed
Ensure that the relationships and constraints between the sketches are maintained

To perform analysis tests in SolidWorks or ANSYS, follow these steps:
Import the structure into the software
Define the material properties
Apply appropriate boundary conditions
Set up the analysis type (static, dynamic, thermal, etc.)
Define the loads and constraints
Mesh the structure
Run the analysis
Review the results and interpret them
Make necessary design modifications based on the analysis

I applied via Naukri.com and was interviewed before Jul 2020. There was 1 interview round.
Name mangling is a technique used by compilers to give unique names to functions and variables to avoid naming conflicts.
Name mangling is used in C++ to support function overloading.
It is also used in Python to avoid naming conflicts in modules.
Name mangling can make it difficult to access variables and functions from outside the class in which they are defined.
In C++, name mangling can be seen by using the 'nm' comman
I applied via Naukri.com and was interviewed in Aug 2020. There were 3 interview rounds.
Abstract Factory is a creational design pattern that provides an interface for creating families of related objects.
Abstract Factory is used when we need to create families of related objects without specifying their concrete classes.
It provides an interface for creating objects of related classes without specifying their concrete classes.
It encapsulates a group of factories that have a common theme.
It promotes loose c...
Range based map iteration can be done using a for-each loop or iterators.
Use a for-each loop to iterate over the map elements.
Alternatively, use iterators to traverse the map.
The range-based for loop is preferred for its simplicity and readability.
Example: for(auto const& [key, value] : myMap) { //do something with key and value }
Detached threads are independent threads that run separately from the main thread. Joined threads are threads that wait for the main thread to finish.
Detached threads are created using pthread_detach() function
Joined threads are created using pthread_join() function
Detached threads do not need to be explicitly terminated
Joined threads must be explicitly terminated using pthread_exit() or return statement
Detached thread...
Static code analysis tools are software programs that analyze source code to find potential issues and improve code quality.
Static code analysis tools scan code without executing it
They can detect issues such as security vulnerabilities, coding errors, and performance problems
Examples of static code analysis tools include SonarQube, ESLint, and Checkstyle
Command to list currently running threads in linux
Use the 'ps' command with the 'H' option to display threads in a hierarchy
Use the 'top' command to display threads in real-time
Use the 'htop' command for an interactive display of threads
No, arithmetic operations cannot be performed on unique pointers.
Unique pointers are used to manage the lifetime of dynamically allocated objects.
They cannot be copied or assigned, only moved.
Arithmetic operations are not defined for pointers, including unique pointers.
Designing Facebook is a complex task involving various components and technologies.
Identify the core features of Facebook such as user profiles, news feed, messaging, and groups.
Choose appropriate technologies for each component such as PHP for backend, React for frontend, and MySQL for database.
Ensure scalability and performance by implementing caching, load balancing, and database sharding.
Implement security measures...
