3. Water flows through a circular channel that has a diameter of d= 75 mm at both the inlet and outlet, as shown below. The fluid enters with uniform velocity U = 7.5 m/s. The channel makes a 90° bend that distorts the flow to produce the velocity profile at the outlet described by the function, v(r) = Vmax ( 1 -722 Assume steady, incompressible flow. Density of water is 1000 kg/m² a) Find the value of Vmax. b) Find...

An incompressible fluid flows between two porous, parallel flat plates as shown in the Figure below. An identical fluid is injected at a constant speed V through the bottom plate and simultaneously extracted from the upper plate at the same velocity. There is no gravity force in x and y directions (g-g,-0). Assume the flow to be steady, fully-developed, 2D, and the pressure gradient in the x direction to be a constant P = constant). (a) Write the continuity equation...
