[Unified-mailman] F20 clarification

[Carl Dietrich]

Students,

	In problem F20 part b you are asked for the "minimum" exhaust pressure to ensure the independence of the upstream flow -- the question should ask for the threshold exhaust pressure that you are looking for (not the minimum).   Come by office hours if you are confused by this distinction.

-Carl
