Problem 4. As shown in the figure, steam at 80 bar, 440 °C, enters a turbine operating 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, 400 °C. 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. Py-80 har 7₁-440°C (AV), -236 m/min 0.20 P60 bar 7₂-400°C D₂-0.25 m x=0.90 P=0.7 har D₂-15 m Problem 4.
