Answer a) and b)

1. An incompressible Newtonian liquid is in steady laminar flow in a slit
formed by two parallel vertical walls separated by a distance 2B. The
walls have a length L and a width W. Since B<W and B « L, edge
and end effects are not important. The flow can be considered fully
developed and the velocity will vary only in the x-direction. The
pressure at the entrance is Po and at the exit PL.
Fluid in
Note the location of the coordinate system in which x = 0 is located
midway between the two vertical surfaces.
2B -
(a) Write the simplified form of the Navier-Stokes equation that
will be used to solve for the velocity profile vz.
(b) Write the two boundary conditions that will be used to obtain a
solution for the velocity profile.
(c) Obtain a solution for the velocity profile vz as a function of x in
terms of Po, PL, P, g, µ, L and B.
(d) Determine the maximum velocity and its location.
(e) Obtain equations for the volumetric flow rate and average velocity.
What is the relationship between the average and maximum velocity?
