Consider the flow of air through a convergent-divergent duct, such as the venturi described in the problem above. The inlet, throat, and exit areas are 3 m2, 1.5 m2, and 2 m2, respectively. The inlet and exit pressures are 1.02 x 105 and 1.00 x 105 Pa, respectively. Calculate the flow velocity at he throat. Assume incompressible flow with standard sea level density.
