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...

Water flows steadily along a horizontal open channel of uniform width, over a broad-crested weir. The channel bed upstream from the weir (to the left) is d -0.75m above the channel bed downstream from the weir (to the right), as shown in the figure below. The volume flow rate per unit width is Q 6m2 s-1, and the downstream depth of the water is ћ2-d. Take the magnitude of the acceleration due to gravity as g 10ms-2. d - 0.75...

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...

You are conducting a wind tunnel test to measure the aerodynamic drag ("air resistance") over a cylinder. Apply the momentum principle for a control volume to relate the drag force per unit width, w, in terms of the upstream and downstream velocities and pressures. The upstream velocity is a uniform 15.6 m/s. The downstream horizontal velocity measurements are shown in the table below. Upstream pressure is 133.5 Pa (gauge) and downstream pressure is 0.0 Pa (gauge). The diameter of the...

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

P.2 Fluid flows steadily between two infinitely large plates separated by a distance of h, as shown below. Flow is driven by a pressure gradient in the x-direction, with the pressure decreasing from left to right. Both plates are held still. a) Find and plot the velocity profile between the plates, and b) determine the force per unit area (F/A) exerted by the fluid onto the plates (magnitude and direction). Hint: Find the magnitude of the shear stress at the...
