As shown in Fig. P4.19, 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.
P1 = 80 bar
