It all about Energy..

 

Assalamualaikum and a very good day. Hye!!

For this time, we will explain about the Energy, Energy Transfer and General Energy Analysis.

The image shown explain simple about the theory of energy transfer relate to the First Law of Thermodynamics. For more revision of others law you may refer to the image below here. =D

Here some of heat transfer and it specific formula

Next.. the image below shown about the Macroscopic Energy, they are Potential Energy and Kinetic Energy and Flow Energy

If you do not know or forget about what it is Kinetic Energy, Potential Energy and Flow Energy..here are some figure.

Before going futher.. here are some important tips that you need remember in remarking the "sign convention" of Heat and Work. Otherwise, you will get wrong for you calculation answer.

The image below shown about the formula of Internal, Kinetic and Potential Energy Changes.

The energy content of a control volume can be changed by mass flow as well as heat and work interactions.

Before we go futher about the calculation.. here are simple explanation about the Polytrophic Process.

Polytrophic process mean, process on any open or closed system of gas or vapor which involves both heat and work transfer, such that a specified combination of properties were maintained constant throughout the process

Next.. here are some calculation about work done of gas.
