MAE 101A Fluid Mechanics, Winter 2008 Regarding Midterm 1 Closed book. Closed notes. No calculator. There will be 3 problems. Summary of Material Chap. 1. Introduction Sections 1.1-1.11 Continuum description. Velocity vector field. Streamlines, pathlines and streaklines. Material properties: density, viscosity, surface tension. Shear stress for a Newtonian fluid. Reynolds number, Mach number. Some flow classifications: Viscous/Inviscid, Laminar/Turbulent, Internal/External, Compressible/Incompressible. Chap. 2. Fluid Statics Sections 2.1-2.10 The basic equation of fluid statics. Pressure variation in a compressible fluid. Manome- ters. Forces and moments on submerged bodies: plane surface, curved surface. Pres- sure variation in rigid body motion (not included for midterm but included for final).
