As shown in the figure, steam at 1200 psia, 825°F, enters a turbine operating at steady state with a volumetric flow rate of 8334 ft3/min. Twenty percent of the entering mass flow exits through a diameter of 0.8 ft at 900 psia, 750°F. The rest exits through a diameter of 5 ft with a pressure of 10 psia and a quality of 90%. Determine the velocity at each exit duct, in ft/s.
