Question
The streamlines in a particular two-dimensional flow field are
all concentric circles, as shown in Fig. 5
the equation v, = wr where w is the angular velocity of the rotating
mass of fluid. Determine the circulation around the path ABCD.
The velocity is given by
B

The motion of a liquid in an open tank is that of a combined
vortex consisting of a forced vortex for 0 <r<2ft and a free vor-
tex for r > 2 ft. The velocity profile and the corresponding shape of
the free surface are shown in Fig. 6 . The free surface at the cen-
ter of the tank is a depth h below the free surface at r = o. Deter-
mine the value of h. Note that h = hforced + h&ce Where hforced
and hfee are the corresponding depths for the forced vortex and the
free vortex, respectively.
