Problem 2 Find the velocity profile for steady, fully-developed, laminar flow in a circular pipe. Integrate this velocity profile to find the mass flowrate through a pipe of length L for a given pressure drop Ap.
5. In a fully developed fluid flow in a tube, which following statement(s) is(are) true(12 points): a) the velocity profile varies with the axial distance z. b) the flow will change from laminar to turbulent flow c) The velocity gradient with respect to r (dv/dr) is zero at the centric line of the tube. d) The velocity is zero at the wall of the tube. Developing
Part 4: Viscous Flow Concepts (10 points,5 each) The flow through a duct is fully-developed, with a velocity profile as shown in the figure. has a rectangular cross section, and the velocity profile is uniform in the z-direction (it does not change going into the page) If we wish to determine the mass flow rate through the duct, which differential area would we use? Why? If we wish to determine the forced caused by shear stress on the bottom wall,...
For a fully developed pipe flow, which of the following does not remain constant in the direction of flow? O Mean velocity Mean temperature Dimensionless temperature difference Local convection coefficient
Question 10 Fully-developed steady lamina fowistven o the x-direction. The upper plate is szereyado Uw Assume thatv-Oz were heren before that steady, Neglect body forces. To solve this problem, you will use the one @u -+ at au - +- a au os au - =- = For the flow described above, mark All boundary velocity profile U=Oatyo Uwall aty aty Uwalay
If the magnitude of B⃗ increases while its direction remains unchanged, how will the magnetic flux through the coil change?
Water is in steady fully developed laminar flow between two horizontal, very wide (W) and long (L) parallel surfaces separated by a distance b. The bottom surface at y 0 moves in the negative x-direction at a speed vo while the top surface at y b is stationary. In addition, a constant pressure gradient dP/dx is acting on the liquid in the x-direction. (a) Write the simplified form of the Navier-Stokes equation and the appropriate boundary conditions. (b) Derive an...
the flowing is true or fuels with correct Catalyst may change chemically but remains unchanged physically
