Unformatted text preview: point out how very wrong the incompressible area/velocity relation is when dealing with compressible ﬂow. We’ll get to shock waves for real later on. 5. Will we ever use the control [illegible] form of the 1st law in ﬂuids? (1 student) Sorry, couldn’t decipher the question. We will apply the 1st law in control-volume form shortly. 6. How are boundary layers aﬀected by high speeds? (1 student) Surprisingly little. A boundary layer at Mach 2 looks a lot like a boundary layer at Mach 0.1, except the Mach 2 b.l. is warm from the frictional heating. It’s also a bit thicker for a given Reynolds number than in low speed ﬂow, but not by much. 7. No mud (8 students)...
