WebFlow through Steam Nozzles. 9/19/2024 4 Flow of Steam through Convergent-Divergent Nozzle 1. The steam enters the nozzle with a high pressure, but with a negligible velocity. 2. In the converging portion (i.e. from the inlet to the throat), there is a drop in the steam WebQuestion: Q6. Superheated 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 240∘C and 350kPa and the velocity is 30 m⋅s−1. At the nozzle exit (state 2), the steam temperature and pressure are 325∘C and 700kPa.
