Question

As shown in Fig., steam at 80 bar, 4408C, enters a turbine operating at steady state with a volumetric flow rate of 236 m/min. Twenty percent of the entering mass flow exits through a diameter of 0.25 m at 60 bar, 4008C. 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 Exit 3 duet, in m/s.
