Assalamulaikum.
Principle chemical process 2 and again with our Prof Dr Azeman. It’s a please to have him as our lecturer as he thought us principle chemical process 1 before during the first year. Luckily, I pass my PCP1 and can continue with PCP2. I admit that it’s a thought subject, moreover this time it including energy balance and thermodynamic. We are the first batch for this syllabus and I hope that we can do this subject excellently.
We enter the first class on 11th sept and our lecturer told us all about this new subject to our courses. It may be easier than before because energy balance but much harder when includes thermo. The first chapter that we learned is Chapter 8, Balance On Non Reactive Process. And we are still using the old book which is Elementary Principle Of Chemical Process. There are two important thing that I learned in this chapter which are the first law of thermodynamic.
Closed systemQ-W = ^U + ^KE + ^PE
Open system Q-W = ^H + ^KE + ^PE
It seems much easier that what I learned on the last semester. I can understand it much easier, so I hope I can score the upcoming test. There are also some table need to be refer to answer problem in this chapter such as table B1,B2 until B7. Im impressed how these table can help us in calculating many thing. I doenst know the function of the graph before.
The last part that seems hard for me to understand is Psychometric Chart . It takes time to understand this part better.It is important to know that the chart is only for water and dry air.Now I know how to find dry-bulb temperatue, absolute humidity, relative humidty, dew point, humid volume, wet-bulb temperature, specific enthaphy andenthalphy deviation.
Lastly is adiabatic humidification. What I know about humidification is it add moisture to the air which increase the absolute humidity while dehumidication is remove the moisture.
I thinks that all that I want to share about this chapter. It look easy but it takes time to really understand what it is. Exercise also needed. I hope I can improve my understanding by doing the assignments and quizzes given. Lastly, I hope that my journey on this course will be smooth and I can score on the final exam .
