Compressible Flow Class Absence
 Comment by Prof. Parent If you can't make it to class, mention it in this thread the morning before class time or one day ahead. Tell us which class you will miss and why you can't make it. If you are going on a conference trip, you need to notify me at least 10 days ahead of time.

 Comment by Prasanna Professor, I have to visit the Busan Immigration Office to register my fingerprints for my Alien Registration Card on $20^{th}$ September (Thursday). The scheduled time is 2-5 PM and the time taken for fingerprint registration is said to be a few minutes, but a long waiting time is to be expected. So I may not be able to attend the class on time. Please forgive me if I do not make it to the class on time.

 Comment by Prof. Parent That's ok, no problem.
 Comment by Student 201893243 I will be attending Intel seminar in Seoul next Tuesday. So I think I will be out of class next week. I will ask the students in the same laboratory to arrange the contents of the class.
