Steam flows at steady state through a converging, insulated nozzle, 25 cm long and with an inlet diameter of 5 cm. At the nozzle entrance (state 1), the temperature and pressure are 325°C and 700 kPa and the velocity is 30 m-s-1. At the nozzle exit (state 2), the steam temperature and pressure are 240°C and 350 kPa. Property values are: H1 = 3112.5 kJ-kg-l H2 = 2945.7 kJ·kg- V1 = 388.61 cm³-g-l V2 = 667.75 cm³.g=l What is the velocity of the steam at the nozzle exit, and what is the exit diameter?
