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).

Unformatted text preview: • Important Fluid Mechanics Formulae you need to know Equations for streamline, pathline, streakline. Relation between shear stress and shear rate. The basic equation of ﬂuid statics. Ideal gas equation of state. Calculation of hydro-static force on a plane surface and a submerged surface. Modiﬁcation to the basic equation of ﬂuid statics by rigid body acceleration. • Following formulae and information will be given to you during the exam if required Center of pressure, Eq (2.29) and axes as in Fig. 2.11. Moments of inertia will be provided. y CP =-I xx sin θ h CG A x CP =-I xy sin θ h CG A...
