Problem 3. Consider the steady flow of air between parallel disks as shown. Assume that the flow is
incompressible and inviscid, and that the velocity is purely radial and uniform at any section for r>=r_(i) where
r_(i)=2.5cm. The flow speed is V=15(m)/(s) at R=7.5cm. (a) Calculate the velocity at r=r_(i) by simplifying
the continuity equation for this flow field and showing that a general expression for the velocity field is given by
vec(V)=V((R)/(r))hat(e)_(r) for r_(i)<=r<=R. (b) Calculate the acceleration of a fluid particle at the locations r=r_(i) and
r=R. (c) Briefly discuss how the velocity and acceleration change for this steady flow with radial direction.
