Tutorial 5, Week 7
24 & 26 April 2012
Exercise 1
It is known that a vortex plus a sink can simulate a tornado as shown in Fig (1). Suppose that the circulation about the
tornado is = 8500 m2 /s and that the pressure at r = 40 m is 2200

1 and 3 May 2012
Exercise 1
The viscous, incompressible ow between parallel plates shown in Figure 1 is caused by both the motion of the bottom
plate (at velocity U ) and the pressure gradient, p/x. As noted in Section 6.9.2
