EGN 6812 - Fluid Mechanics I – Fall 2004 11/30/04, Exam #2 Name: _________ ____________ 1/9 Questions: (40 points total, 3 points each, unless otherwise marked) 1. State the 3 methods (and their respective assumptions) discussed in class of deriving Bernoulli’s equation (6 points) . 2. For inviscid flow around a bend, does the pressure increase, decrease, or remain the same in the outward direction from the bend (or radius of curvature is increasing)? 3. What are the conditions under which both the streamfunction and the velocity potential can be defined for a spherical coordinate system ? Will both satisfy Laplaces’s equation? Questions: (40 points total, 3 points each, unless otherwise marked)

EGN 6812 - Fluid Mechanics I – Fall 2004 11/30/04, Exam #2 Name: _________ ____________ 2/9 4. For flow in a duct driven by an oscillatory pressure gradient there is an overshoot in the velocity profile near the wall (i.e., the maximum velocity profile does not occur at the center line. Physically describe why this occurs. 5. In ideal flow, it is common to employ superposition solutions of various individual solutions to Laplace’s equation in terms of the streamfunction and/or velocity potential. Is it also valid to superimpose pressure fields of each individual solution? Please justify your answer mathematically and/or physically.
