Question

Let the vortex/sink flow of Eq. (8.16) simulate a tornado as inFig. P8.25. Suppose that the circulation about the tornado isT = 8500 m²/s and that the pressure at r40

m is 2200 Paless than the far-field pressure. Assuming inviscid flow at sea-level density, estimate (a) the appropriate sink strength -m,15 m, and (c) the angle B at which the40 m (see Fig. P8.25).(b) the pressure at r =streamlines cross the circle at r =
