Determining Overall Mass Transfer Coefficient for Gas Phase
Question
Water is used to absorb the vapor of methanol at 300 K and 101.325 kPa. The concentration of methanol in both gas and liquid phases are very low, with the equilibrium relation following Henry’s Law. The known parameters are:
solubility of methanol in water = 1.995 kmol/(m3 .kPa)
local mass transfer coefficient for gas film kG = 1.55E-5 kmol/(m2.s.kPa)
local mass transfer coefficient for liquid film kL = 2.08E-5kmol/(m2.s.kmol/m3)
(1) Please determine the overall mass transfer coefficient for gas phase, KG,
(2) And determine the percentage of mass transfer resistance in gas film out of the overall resistance.
(3) At steady operation in certain section of the absorption column, the partial pressure of methanol is 5 kPa and the liquid composition is 2.11 kmol/m3. Please determine the methanol absorption rate NA, [kmol/(m2.h)] .
Summary
This question belongs to thermal engineering and discusses about mass transfer and absorptions.

WHAT OUR STUDENTS SAY
1. Being a computer science engineer is my dream and it wouldn’t have possible for me to minutely understand the basics of C++ programming without the help of TheReliableTutor.com and the engineering assignment tutors. I grasped C programming on my own, but for C++ and Java, I am definitely grateful to TheReliableTutor
Joseph Gordon Student
1. When I tell the online accounting assignment help expert what I am looking for from the assignment solution that is exactly what I receive from them. Having the understanding of how the universities and professors work in Singapore is definitely a plus for the online Singapore accounting assignment help experts at HwA.
Jia En Koh Student
I was really very poor at drawing phase diagrams in my material science course. In fact that was the first time I looked for help from HwA. The result was fantastic. The material science experts knew what to deliver just after receiving the request and I didn’t have to worry since then.
Kate Green Student
I took constant help from HwA for mean, median and mode assignments of random variables and I am very happy with the feedback I get from my professor. The statistics experts at HwA are very helpful and they assisted me to get good grades in all my random variable assignments.
Chris Mathew Student
The coding is without flaw and only minor changes may have to be made now and then in the Programming assignment help that I have been receiving from TheReliableTutor. The packages are very affordable, that coupled with the highly qualified and professional online programming assignment experts residing in Singapore has definitely helped me get the top grades and hassle free services.

this is a very good website
I have 50 questions for the same test your page is showing only 28
hi can you please help or guide me to answer my assignments. thanks
hi can anyone help or guide me to my assignments. thanks
This solution is perfect ...thanks
Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
