Home looking Files X Exam2(2).pdf + Exam2%20(2).pdf 4/4 3. An incompressible, viscous fluid with density, p, flows past a solid flat plate which has a depth, b, into the page. The flow initially has a uniform velocity U... before contacting the plate. After contact with the plate at a distance x downstream from the leading edge, the flow velocity profile is altered due to the no-slip condition. The velocity profile at location is approximated to have a linear shape, u = 0.fory s 8 and * V. for y > 8, where is termed the boundary layer thickness". () (4 points) Determine the upstream height from the plate, h, of a streamline which has a height, 8, at the downstream distance x Express your answer in terms of 8. () (6 points) Determine the force the plate exerts on the fluid over the distance x. Express your answer in terms of p... b, and 8. You may assume that the pressure everywhere is the force the drag exerts on the plate is called the skin friction" ang Uy>8 streamline plate has depth. b. into the page Solution BB Ten un hey 3
