Mach cone and a sonic boom

Fluid mechanics

o Statics: rgh-pressure, Archimedes principle, Pascal’s principle

o Fluid dynamics

o Continuity equation

o Bernoulli’s equation

o Applications

Reminders:

o Read chapter 18. Do hw14. Your goal is to complete hw14 as much as possible on your own, by the Wed before Thanksgiving.

o Those of you needs additional explanations, I strongly urge you to come to the Wed’s class, if possible. If you cannot attend, arrange to borrow notes from your classmate who can be there

o Are you concerned about your standing in this class? Please see me after the class or tomorrow after the informal session. Be sure bring your Quest-record with you when you come.

Good participation status(gp-status): As stated in the firstday handout, the gp-status will be evaluated based on student’s pre-final quest-record which will close at 4pm on Monday Dec 8. Student’s verification of the accuracy of his/her record prior to this deadline is a prerequisite to achieve his/her gp status.

To achieve gp-status, again as stated in the firstday handout, this verified pre-final record must satisfy following the triple 80% -criteria.

1. Homework score (after 2-drops) >80%,

2. TA sessions score >80%,

3. Iq-score check > 80%.

a) Iq-score (after 5 drops) >80%.

b) A student can substitute the requirement of 3-a) by having his/her class notes audited during the last week of class. If you want to take this option, you must contact your TA. The classnotes must show an over 80% class attendance and the participation of iq sessions. A more than 20% absence from the class for any reason (including legitimate reasons) will automatically disqualify from consideration of the gp-status. If a student with a low iq-score has passed the audit, his/her iq-score will be converted to 80%.

Notice option b) is intended as a safety-net to take care of exceptional cases. Since presently the quest-clicker record is working, I expect the number of requests for using this option should be reduced to very few, if at all.
