Then a uniform stream flows past an immersed thick cylinder, a broad low-velocity wake is created down- stream, idealized as a V shape in Fig. P3.44. Pressures p1 and p2 are approximately equal. If the flow is twodimensional and incompressible, with width b into the paper, derive a formula for the drag force F on the cylinder. Rewrite your result in the form of a dimensionless drag
Determine the change in pressure for an adiabatic process using Argon that has an initial volume of 105-in3 and an initial pressure of 19-psia and a final volume of 19.1-in3.
Consider the flow of a uniform stream of speed V in the x-direction and a sink of strength Q at the origin. Find the stagnation point(s) and the equation of the stagnation streamline. Sketch (freehand) the flow streamlines
