3. (Problem 4.29 on main book) In the incompressible flow through the device shown, velocities may be considered uniform over the inlet and outlet sections. The following conditions are known: A1 = 0.1 m² , A2 = 0.2 m², A3 = 0.6 m², V1 = 10 expet/2 m/s, and V2 = 2cos(2nt) m/s (t in seconds). Obtain an expression for the velocity at section (3), and plot V3 as a function of time. At what instant does V3 first become zero? What is the total mean volumetric flow at section (3)?
