Steam at 80 bar, 440oC enters a turbine at 1operating at steady state with a volumetric flow rate of 236 m3/min. Twenty percent of the entering mass flow exits through a diameter of 0.25 m, at 60 bar, 400oC. The rest exits through a diameter of 1.5 m with a pressure of 0.7 bar and a quality of 90%. Determine the velocity at each exit duct, in m/s.
