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?

Question
  1. Energy Balance in an Open System

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?
