10th, 11th & 12th classes (Febr. 20, 25 & March 3): Forces on curved gates & buoyancy; Reading assignment: pp. 81- 86.
Correction in textbook: In Fig. 3.25 (a) (on p. 82), the distribution of the shown
elementary pressure forces
should be of increasing magnitude as the depth increases.
13th and 14th classes (March 5 & 10): Eulerian vs. Lagrangian description of flow; streamlines, pathlines, streaklines; flowrate, mass rate, & continuity equation; Reading assignment: pp. 104-113, pp. 154 -173 (except Reynolds Transport Theorem on pp. 164 -166)
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.
