2. Wind blowing past a flag causes it to "flutter in the breeze." The frequency of this fluttering, f, is assumed to be a function of the wind velocity, V , the air density, rho, the acceleration of gravity, g, the length of the flag, l, and the "area density" (mass per unit area) of the flag, WA. Find the appropriate Pi groups to characterize fluid mechanics phenomena that causes the fluttering.
