74. The volume rate of flow is R = vA where A = π r 2 and r = d /2. Solving for speed, we obtain 22 4 . (/ 2 ) R RR v Ad d ππ == = (a) With R = 7.0 × 10 –3 m 3 /s and 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:
