Liquid water flows isothermally at 75oF through a one-inlet, one-outlet duct operating at steady state. The duct's inlet and exit diameters are 5.0 and 7.0 inches, respectively. At the inlet, the velocity is 40 ft/s and the pressure 15 psia. At the exit, determine the mass flow rate, in lbm/s, and the velocity, in fps.
