Steam at 80 bar, 440 0C, enters a turbine operating at steady state at a volumetric flow rate of 180 m3/min. The water exits the turbine in two streams, 20% as exits through a 0.25 m diameter pipe at 60 bar, 400 0C. The rest exits through a 1.5 m diameter pipe at a quality of 85%, 0.7 bar. Determine the mass flow rate at the inlet in kg/s and velocity in each of the exit pipes in m/s.
