Fundamentals of Fluid Mechanics B Questions and Answers  


In A5Q3, there is no reason to use the streamfunction. Rather use the derived drag force on a sphere outlined in the tables.




Something is wrong. Make sure you write down your drag force correctly.






Download the latest version of the tables. At the bottom of the last page, there is a link that you can click to access the source files.




For part (a), you need to outline a condition when this term is negligible. So, you need to compare its magnitude to the magnitude of another term in the same transport equation. In part (b), find the error simply as the ratio between this term and the other term to which it is compared to. Use order of magnitude analysis and substitute values for $u$, $\rho$, etc using the freestream properties.




Will look into it.
