Steam flows at steady state through a converging, insulated nozzle, 35 cm long and with an inlet diameter of 2.5 cm. At the nozzle entrance (state 1), the temperature and pressure are 250 °C and 1000 kPa, and the velocity is 20 m/s. At the nozzle exit (state 2), the steam temperature and pressure are 700 °C and 400 kPa. Property values are H1 = 2942.59 kJ/kg                                         H2 = 3926.53 kJ/kg V1 = 0.23268 m3/kg                                         V2 = 1.12147 m3/kg What is the velocity of the steam at the nozzle exit, and what is the exit diameter?
