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.

A S.I./C.I. engine is a type of internal combustion engine that operates on either spark ignition or compression ignition.
S.I. engine stands for Spark Ignition engine, where the fuel-air mixture is ignited by a spark plug.
C.I. engine stands for Compression Ignition engine, where the fuel-air mixture is ignited by the heat of compression.
In a S.I. engine, the fuel-air mixture is drawn into the cylinder during the intake...
The inlet valve is opened before TDC to allow fresh air-fuel mixture into the combustion chamber. The spark plug is positioned at a specific angle for efficient combustion.
Opening the inlet valve before TDC ensures that the piston is moving downwards, creating a pressure difference that helps in drawing the air-fuel mixture into the combustion chamber.
This timing also allows for better mixing of the air and fuel, leadi...
Changing the angle can have various effects depending on the context.
Changing the angle can alter the direction or trajectory of a moving object.
In physics, changing the angle of incidence can affect the amount of reflection or refraction of light.
In engineering, changing the angle of a structural component can affect its stability or load-bearing capacity.
In mathematics, changing the angle can affect the trigonometric...
A braking system is designed to slow down or stop the motion of a vehicle or object.
Braking systems use friction to convert kinetic energy into heat energy.
Common types of braking systems include disc brakes, drum brakes, and regenerative brakes.
Disc brakes use calipers and brake pads to clamp down on a rotating disc, creating friction and slowing down the vehicle.
Drum brakes use brake shoes that press against the insi...

The cost of Ceria bed used in the design of a catalytic converter is lower than the bed used in available catalytic converters.
Ceria is a cost-effective material for catalytic converters.
It is widely used in the automotive industry due to its affordability.
Compared to other beds used in catalytic converters, Ceria offers a more economical solution.
The lower cost of Ceria bed does not compromise the performance of the c
The rectangle will have greater load bearing capacity in the vertical position.
The load bearing capacity of a rectangle depends on its orientation.
In the vertical position, the weight is distributed along the longer side, resulting in greater load bearing capacity.
In the horizontal position, the weight is distributed along the shorter side, resulting in lower load bearing capacity.
The vertical position allows for bette...
