Q2: Steam enters a converging-diverging nozzle operating at steady state with
Pi=40 bar, T-400C, and a velocity of 10 m/s. The steam flows through the
nozzle adiabatically and no significant change in elevation. At the exit, p:=1.5
MPa, and the velocity is 665 m/s. The mass flow rate is 2 kg/s. Determine the
exit area of the nozzle, in (m²). also, drive the (T-V) diagram for the steam.
