Unformatted text preview: r e r R V V ˆ (Q.E.D.) Based on assumptions (2)  (4), acceleration is radial only, and that acceleration is equal to: a pr V r r V r a pr V R r V R r 2 V 2 R R r 3 Therefore, at r = ri: a pr 15 m s 2 1 0.075 m 75 25 3 a pr 8.1 10 4 m s 2 Therefore, at r = R: a pr 15 m s 2 1 0.075 m 75 75 3 (a) simplified version of continuity equation valid in this flow field (b) show that the velocity is described by: (c) acceleration of a particle at r = r i , r = R...
