Question: 2 tavoularis 19 assume that gas bubbles in a glass...

Question details

2. (Tavoularis 1.9) Assume that gas bubbles in a glass of beer rise very slowly. Explain how you would estimate the pressure inside the bubbles by measuring their size.

3. (Tavoularis 1.10) Provide a physical example of supersonic flow with a very small Reynolds number (i.e., less than 1), also provide numerical values for appropriate length and velocity scales.

4. (Tavoularis 1.12) From tables, find the values of the Prandtl number for: a. air at standard temperature and pressure, b. water at standard atmospheric pressure and temperature of i. 4 C ii. 20 C and iii. 80 C, and c. mercury at 20 C. Comment on these numbers.
