Assuming an incompressible, inviscid flow with a uniform freestream as shown in the figure below, tick which one of the following statements are true. (Note: ) a. b. c. d. Depends on the angle of attack 2. Determine the streamline shapes of the following inviscid 2-D velocity field as follows: Solving this differential equation, we get: These represent equations of streamlines as circles of radius √ . 3. For the above field, evaluate the material derivatives and ; and evaluate the pressure gradient . Assume the flow is incompressible without body forces. From the momentum equations in and direction (no viscous/body forces), we have: ( ) () ⃗ ⃗ ⃗ ⃗...
