LABS start the week of September 10, 2018, and will be held EVERY week. Make sure you visit the
Lab website
and print the corresponding documents BEFORE each lab.
10th, 11th & 12th classes (Oct. 2, 4, and 11): 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 (October 16 & 18): 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.
