E-Portfolio Principle of Chemical Process (II) for test 1 Hanis Syairah Sazali
Due to the bad results of PCP (II) in test 1, we are required to do some reflection about all questions in the test…huhu.. 
so that we are learnt from our mistakes. For the test 1, the marks that I obtain not reaching half of 100%. In general, I think the real reason that I cannot gain the higher marks because of the incomplete CO1 which is the basis is not completed with the reference condition of the compounds involved. Secondly, the basic of mass balance is not strong enough to solve the problems.
For question 1, it is not difficult for me to understand the question because the question quite straight to the point. But I have loss marks in solving the (a) part. I cannot really figure out the right words to explain about the hypothetical path.
For question two, I have a problem to search for the temperature of the water outlet from the heat exchanger. Thus, all of the question cannot be solved. The temperature can be gain in appendix B7 for the temperature of 5 bar. Then, by using all of the component involved, construct the enthalpy table to calculate the mass of steam.
For question 3, I only get the marks for the basis. I have big problem in solving the mass balance. For this question, I should use the psychometric chart to obtain value for the mass dry air. In this question, the key words is adiabatic which mean Q=0. Then solve by using formula QWater = -QDA.
Same for the last question, I only get marks for the basis for question 4. To solve the question, I suppose to calculate the value of P by using dry cereal balance. Then find the mass of water and humidity. Mass dry air is equal to mass water divided by humidity. Volume Ai = Volume MDA.
The most important things that will help me to score in next test is the basis, reference state and the mass balanced. I have to master it first to make my life getting easier in solving a problem.
