Explanation of velocity and shear stress profiles for circular pipe and Couette flow with boundary conditions.
Velocity profile for circular pipe is parabolic, while for Couette flow it is linear.
Shear stress profile for circular pipe is also parabolic, while for Couette flow it is constant.
Boundary conditions for circular pipe include no slip at the wall and constant pressure at the ends.
Boundary conditions for Couette...
The energy equation is a mathematical representation of the conservation of energy principle in various forms.
The energy equation states that the total energy of a system remains constant.
It includes terms such as kinetic energy, potential energy, internal energy, and work done.
Kinetic energy is the energy possessed by an object due to its motion.
Potential energy is the energy stored in an object due to its position or...
Temperature profile over a flat plate becomes parabolic due to the energy equation.
The energy equation describes the conservation of energy in a fluid flow.
For a flat plate, the energy equation simplifies to the heat conduction equation.
The heat conduction equation is a second-order partial differential equation.
The solution to the heat conduction equation for a flat plate yields a parabolic temperature profile.
This pa...
Explanation of engineering and true stress strain graphs and their different regions.
Engineering stress-strain graph shows the relationship between stress and strain during deformation of a material.
True stress-strain graph takes into account the reduction in cross-sectional area of the specimen during deformation.
The different regions in the graph are elastic region, yield point, plastic region, necking and fracture.

Compression problem
Compression is the process of reducing the size of data to save storage space or transmission time.
Common compression algorithms include ZIP, GZIP, and DEFLATE.
Lossless compression retains all the original data, while lossy compression sacrifices some data to achieve higher compression ratios.
Compression can be applied to various types of data, such as text, images, audio, and video.
Compression techn...
During my final year project, I had to work with a programming language that I was not familiar with.
I had to spend extra time learning the language and its syntax
I had to seek help from my peers and online resources
I had to constantly test and debug my code to ensure it was working correctly
I had to adapt to a different coding style and approach
Despite the challenges, I was able to successfully complete the project an

Program to find last non-repeating character in a given string using Java 8 functions only.
Use Java 8 Streams and Lambda's to filter the string and find the last non-repeating character.
Create a Map to store the frequency of each character in the string.
Use the filter() method to get the non-repeating characters and find the last one using reduce().
Find the top 3 employees based on ratings in an employee table.
Sort the employee table based on ratings in descending order.
Select the top 3 employees from the sorted table.
Return the selected employees as the result.
Modify Employee class to consider objects with same names as duplicates.
Add a static HashSet<String> to keep track of unique names.
Override equals() and hashCode() methods to compare names.
In the constructor, check if the name already exists in the HashSet and mark it as duplicate if true.
