Correction in textbook: In Fig. 3.17 (a) (on p. 53), the distribution of the shown
elementary pressure forces
should be of increasing magnitude as the depth increases.
Instantaneous vs. mean turbulent flow around a sphere . The effect of a ring at the upstream part of the sphere on the flow is also shown.
The Reynolds number R (or Re) is a non-dimensional number defined as U*D/nu, where U=speed upstream, D= diameter of sphere, and nu=kinematic viscosity
of the fluid.
