Reflection | Principle of Chemical Process II (reflection journal) by adillafindi

hello hello hello!

ouh ya.. chapter ni ade cerita pasal:

• power system
• rankine cycle
• effect of pressure and temperature on the rankine cycle
• deviation of the actual cycle from ideal cycle
• the Vapor compression refrigeration cycles
• deviation of the actual capor-compression refrigeration

thank you to dr. aznizam for being my lecturer for this subject. i'm glad to have you.. thank you for teaching me. 

salam alaik...

as a students, i should be ABLE to define the entropy, know the entropy of a pure substances , entropy generation and also the efficiency.

actually i'm not really understand this chapter. but, i think in this chapter i need to be more creative to get an idea to answer the question. all the assignment and quizzes that had given by Dr. Aznizam are really helpful.

TEST 3

hurm.. for question 1 and 2 i am able to do.. but i think i loses mark on question 3 and 4. (xtaw pon..sebab x dapat paper lagi..hahahaha..agak2 je).

ouh ya! i am a little bit confsed about the isentropic. so i think i should study and focus on it.  .(focus final ni!)

hurm.. hurm.. hurm.. thermodynamics.. 

my first impression to this topics  easy. hahaha..

but.. it just for a while.. in this chapter we are able to define what is 2nd law of thermodynamics. i learnt about the efficiency of heat engine, heat pump, and refrigerator. after calculate the effieciency, we need to compare with the carnot. so that we know the system are effience or not.

 yg ni best lagi... lepas ni bru msk entropy...

chapter 9... in this chapter i had learnt about heat of reaction, hess's law, heat formation and heat of combustion. 

heat of reaction can be calculated using hess's law and heat of formation. Dr. Aznizam preferred their student to use heat of formation. this is because this method is easy to understand. it depends. 

TEST 2... 

this test had covered all the chapter 9 topics. alhamdulillah its better than test 1. but my mark had been deducted (5m) because i'm used a wrong method for the last question. it was realy bad because i did not read the question carefully. 

and also.. in this chapter we must MASTER the mass balance. wow! :)

objective:

student should be able :

• compute heats of formation from experimental data for the enthalpy change of a process with reaction taking place.
• calculate heat of reaction.
• apply general energy balances.

Test 1 is covered only for chapter 8. so.. we need to expert how to read the psychometric chart. i understand about the psychometric chart because the way Dr Aznizam deliver is really good. 

In chapter 8, we as the students should define the variable heat capacity in constant volume,heat capacity at constant pressure, heat melting and heeat of vaporization. During the class, students give a full attention about this topics. 

we are also learn about Kopp's rule to estimate the heat capacity of a liquid and solid species.

today is my 1st class of principles of chemical processes. i'm in section 08. meet a new lecturer for this subject Dr. Asnizam.

what i have learn in class last tuesday morning (11.9.12)?

i have learn about chapter 8 which is balances on Non reactive processes. the 1st basic things is references state.  we need 3 important things which is (phase,temperature, and preassure) .

then we are also learn about hypothetical process paths. this only happens when phase is changes. else, the way how to convert the changes from one phase to another phase. for this sub topics, we do not need calculation yet. we just refer to table (at the back of PCP's book).

we got 1 quiz (question) as an excersice in class and also 1 excersices for practices.

-end of class for tuesday morning-
