Superheated steam enters a nozzle that has an inlet diameter that measures 2.5 cm and an outlet
Question:
Superheated steam enters a nozzle that has an inlet diameter that measures 2.5 cm and an outlet diameter that measures 1 cm. Its outlet velocity has been measured at 30 m/s. The steam that enters the nozzle is at 650°C and 1350 kPa and the steam that exits the nozzle is at 400°C and 100 kPa.
A. Determine the velocity of the steam upon entering the nozzle.
B. Determine the rate at which this process gains or loses heat.
C. Example 3-4 and Section 3.6.2 indicate that in modeling a nozzle, it is common to assume the nozzle is adiabatic and that the velocity entering the nozzle is negligible. Do your answers in this case seem consistent or inconsistent with those common assumptions?
