Consider the flow of air through a convergent–divergent duct, such as the venturi tube described in prob. 4.4. the inlet, throat, and exit areas are 3, 1.5, and 2 m2, respectively. the inlet and exit pressures are 1.02 × 105 and 1.00 × 105 n/m2, respectively. calculate the flow velocity at the throat. assume incompressible flow with standard sea-level density. upload your answer via pdf. show all work for full credit.
