2. Water flows over a flat surface at 8 m/s, as shown in figure. A pump draws off water through a narrow slit at a volume rate of 0.2 m2/s per meter length of the slit. Assume that the fluid is incompressible and inviscid and can be represented by the combination of a uniform flow and a sink. a) Based on method of superposition, propose a general expression for stream function ψ velocity potential ф, and velocity components of v,...

For Fluid Mechanics
6. In the figure below, a uniform velocity U approaches an object which extends far into the page, making the flow approximately 2-dimensional. The object causes a wake to form downstream which is idealized as the v-shape shown. If the flow is steady and incompressible, use linear momentum conservation to estimate the force acting on the object per unit width into the paper b. 2 L

To create a vertical wall along the y-axis, one can superimpose two source flows of equal strength Q, centered about the origin on the x-axis at (-x0,0) and (x0,0). Given these two source flows: Determine the potential for this flow field in cartesian coordinates. Determine the streamfunction for this flow field in cartesian coordinates. What value of y corresponds to the wall? Determine functions for the cartesian velocities (u,v) along the wall and show that there is no normal (i.e.,...
