When immersed in a uniform stream, a thick elliptical cylinder (extending a width b into the picture) creates a broad downstream wake with a linear velocity profile having a centerline velocity of Ua=u. u:(9)=0- 4 + ) for Osysl and symmetry in the wake from top to bottom. The pressures at the upstream and downstream sections are approximately uniform and equal. a. Find an analytical expression for the drag force as a function of p, U.,L,b (width of cylinder into...

Consider the situation depicted below, in which an incompressible fluid flows over a flat surface of solid. Upstream of the surface, the fluid has velocity U and uniform temperature To. As the fluid is viscous, both a momentum boundary layer, and a thermal boundary layer form, and heat is transferred to the solid surface. A convective coefficient h can be used to describe the dimensional heat transfer rate to the solid, and is...

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 x is approximated to have a linear shape, u = U. z for y s 8...

Liquid saline flows steadily along the duct in Figure 1, which is part of an infusion set. The duct has constant cross-sectional area Ao-18 mm. The fluid velocity at the inlet section is Vo 0.35 m/s. A drug is added to the saline through a side port connected to the main duct at an angle θ 45°. The cross-sectional area of the side access is A1-10 mm2 and the drug is injected with velocity V,-0.8 m/s. The drug has the...
