2. (10 pts.) Incompressible air enters a circular duct with a uniform velocity $V_1$ and a pressure $P_1$. The velocity at the duct exit has the profile $V_2(r)$ shown below, and a uniform pressure of $P_2$. Using the conservation of mass and momentum, show that the force required to hold the duct is given by: $F = \pi r_o^2[p_1 - p_2 + (\rho/2)V_1^2]$. Hint: Find relationship between $V_{max}$ and $V_1$. $V_2 = V_{max} \left\{1 - \left(\frac{r}{r_o}\right)^2\right\}$
