For me, the interpretation of justice is in terms of giving people equal rights, opportunity, and treatment. This should be applied in all life aspects, so it is needed to understand to know how important social justice is while living in a social life, making a prosperous and formed a fair community life. | On this first meeting, we began our lecturer with discussing the meaning of social justice and its correlation to us, as an engineering student.

On this first meeting, we began our lecturer with discussing the meaning of social justice and its correlation to us, as an engineering student. For me, the interpretation of justice is in terms of giving people equal rights, opportunity, and treatment. This should be applied in all life aspects, so it is needed to understand to know how important social justice is while living in a social life, making a prosperous and formed a fair community life. In taking parts to contribute as an engineer, with education and knowledge that can lead into creating innovations in technology, we may implemented it in terms to advance the less developed areas such as creating power plants to distribute electricity so that all people may receive and having equal access into it.
Our previous discussion about The Law of Conservation of Energy states that energy can not be created or destroyed which is in another words, total energy of a system remains constant. Two basic forms, the kinetic and potential energy both are usually found and applied in our daily life. Back to the basic itself, what is the definition of an energy? If I were given a chance to explain it to an elementary student, or other people that have no opportunity to gain information on that, I would make it as simple as energy is a "fuel" for some object to move. What I mean, those "fuel" is having a process and making an ability so that the object could move. An analogical concept, if people who liked to do such an exhausting sports activity like football or etc, and they did not consume food or drink before doing those activity, will they still be able to move? Normally people will collapse due to exhausted of their energy, The same concept goes into a car, if it were not given a fuel, the car won't be able to move.
All of the engineering courses that we have taken as an engineering student are needed for us to know the importance of its application. For example fluid mechanics as a branch of physics taught us to learn the behaviour of fluid itself and can be applied into many engineering system such as hydraulic, dynamic fluid flow through a pipe, etc.

In energy conversion system, we can convert energy into other form. A combine cycle power plant, for example. The schematic diagram shows that inside a gas turbine the fuel will be combusted, heat recovery system capture the exhaust before the steam turbine delivered additional electricity.
We also managed to learn and were introduce on how to use an operational tools called Openmodelica, In this figure below it shows the structure of the combined cycle power plant :
(1) gas turbine; (2), (4), and (6) HP super-heaters; (3), (5), and (9) IP super-heaters; (11) LP super-heater; (7) HP evaporator; (12) IP evaporator; (16) BP evaporator; (8), (10), (13), and (15) HP economizers; (14) IP economizer; (17) LP economizer; (18) HP drum; (19) IP drum; (20) LP drum; (22) HP pump; (21) IP pump; (23) LP pump; (24) HP steam governor valve; (25) IP steam governor valve; (26) HP steam turbine; (27) IP steam turbine; (28) LP steam turbine; (29) volume; (30) condenser; (31) HP drum-level control; (32) IP drum-level control; (33) LP drum-level control; (34) HP evaporating loop; (35) IP evaporating loop; (36) LP evaporating loop; and (37) electric generator.

We explained our understanding and our point of view about the energy conervation. In physics where the Law of Conservation Energy states that total energy of an isolated system remains constant, which means that energy can neither be destroyed nor created. It can only be transformed or transferred from one form to another. We were given an example about a system from openmodelica where there are two tanks that are connected with a pipe and was filled with a water. This system are related to the bernoulli principle. A system is a group of component that are related to each other so that it can perform on working together to achieve one goal.
In this Bernoulli principle, we knew that pressure plus half of fluid densitiy times velocity square plus fluid density times gravity and the height, for an incompressible friction-less fluid, the following sum will remain constant. When a fluid flows into a narower channel, its speed will increase. Meaning that the kinetic energy also increase. It comes from pressure difference when the channel narrows. Recall that pressure multiply by area equals force, as the result, pressure will drop in a moving fluid. But in this case that the pipe is having the same size from the entry point untill the exit, it can be assume there is no changes in kinetic force. Also it is noted that the height of both tanks are the same.

During this class session, we have a chance to learn on how to use OpenModelica to simulate the result of combustion chamber simulation. There are several components that will be needed as an important role in the simulation listed below:
1. The GT(Gas Turbine)CombustionChamber
2. SourcePQ (Pressure and mass flow is fixed) component for the flue gasses
3. Sink component for the flue gasses
4. SourcePQ (Pressure and mass flow is fixed) for the water steam
5. FuelSourcePQ (Pressure and mass flow is fixed) for the fuel
Unlike the compressor where the air composition remain the same as discussed in 9 March 2021 wiki, the component model of combustion chamber involve the chemical reaction between the air composition from the flue gasses source and the fuel source. Thus, the outlet air composition that will be feed to the combustion turbine will differ from the initial value.
