60. The volume rate of flow is R = vA where A = πr 2 and r = d/ 2. Solving for speed, we obtain v = R A = R π ( d/ 2) 2 = 4 R πd 2 . (a) With R =7 . 0 × 10 3 m 3 / sand d =14 × 10 3 m, our formula yields v = 45 m/s, which is about 13% of the speed of sound (which we establish by setting up a ratio:
