Calculate Nitrogen and Xenon Water Solubility at 50 Bar Pressure
Question
Decompression sickness is caused by dissolved gases coming out of solution in the body as pressure is reduced. To remedy this, gas mixtures with lower solubility are used in diving. At 25°C and 1 bar, the solubilities of nitrogen and xenon in water are xN2 = 1.09 × 10-5 and xXe = 7.69 × 10-5 respectively. Calculate the solubilities of both these gases at 50 bar if the compressibility factors at 25°C are given by
zXe = 1 – 5.16 × 10-3 P – 3.17 × 10-3 P2
and
zN2 = 1 – 9.44 × 10-4P + 1.62 × 10-3 P2
Where P is the pressure in bar. Note that due to expense and narcotic effects, xenon is not suitable for use as a breathing gas.
Summary
The question belongs to Chemical Engineering and it is about calculating the solubilities of nitrogen and xenon gases in water as a solution for decompression sickness as these gases exhibit lower solubility in water. The solubilities of these gases at 1 bar of pressure is given. We need to calculate their solubilities at 50 bar pressure.

WHAT OUR STUDENTS SAY
I am doing a long-distance executive marketing course from a Sydney based University and I really don’t find much time to devote for my marketing assignments. Thankfully, I have come across HwA, and they really know how to deal with these questions. The experts are well equipped and helped me get good grades in all my assignments so far.

Fiona O Farrell: I often lost track of the number of variables and how many equations I needed to evaluate in order to find the values. Then I came across HwA where the experts helped me out with two or three problems and helped me get a feel of how it needs to be done. That extra assistance with my simultaneous equation problems really helped me in the long run and I did well in my final exams.

Ever since I have taken the online taxation assignment help package with TheReliableTutor.com I have never had to worry about missing a deadline or below par quality of essay writing. The tutors are very professional and up to date with the latest happenings in the world of taxation laws. This makes the assignment essays that they help out with one notch higher than the others.
Michael Stark Student
I was apprehensive at first about using an online tutoring service that too for a subject as critical as mechanical engineering. But once I gave it a try I know that I need not have worried. The tutors at TheReliableTutor.com are totally in sync with what is required by me. So we are in a good place

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
