. What equation and Boundary conditions govern this motion?
Show that the Volume flow rate is given by:
________________________________________________________________
BACKGROUND INFO:
Variables:
radius of pipe (r=a)
radius
Governing Equation:
Boundary Conditions:
u(a) = 0
may be 0 in the core.
Therefore,
radius of “no shear” region
rc depends on (y (which is only a function of fluid composition and (P.
=0 (Plug flow)
full equation applies
Boundary Conditions:
@ U=0, r=a
