Steam at 160 bar and 480oC enters a turbine operating at steady state with a volumetric flow rate of 800 m3/min. Eighteen percent of the entering mass flow exits at 5 bar, 240oC, with a velocity of 25 m/s. The rest exist at another location with a pressure of 0.06 bar, quality 94% and velocity 400 m/s. Determine the diameters of each exit ducts in m.
