Steam at 100 bars and 550°C enters a turbine operating in steady-state with a volumetric flow rate of 460 m^3/min. 22% of the entering mass flow exits the turbine at 10 bars, 200°C and a velocity of 20 m/s. The rest exits at a different location at 0.10 bars, a quality of 85%, and a velocity of 500 m/s. Assuming circular cross section pipes, determine the diameter in meters of the exit pipes.
