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 30m⋅s−1. At the nozzle exit (state 2), the steam temperature and pressure are 240∘C and 350 kPa. Property values are: H1=3112.5kJ⋅kg−1H2=2945.7kJ⋅kg−1V1= 388.61cm3⋅g−1V2=667.75cm3⋅g−1 What is the velocity of the steam at the nozzle exit, and what is the exit diameter?
