702 CHAPTER 6. CONTROL-VOLUME METHOD 6.22 Chapter 6, Problem 22 Problem: Consider a sphere of radius R that falls axially through an infinitely long cylinder of radius 8 5 R at a speed U . What is the mean upward velocity of the sur- rounding (incompressible) fluid at the midsection of the sphere? Use a moving control volume to solve. u cv = U k u = u avg n = e r n = k n = k A 1 A 2 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ........................................... . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. .. .. .. .. .. .. .. .. .. .. .. . . . . . . . .. .. . . . . . . . . . . . . . . . . . . . . . . . . . . . .. .. .. .. .. .. .. .. .. .. .. .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
