Using your computer solution from Problem 8.17, vary the outflow pressure from 150 kPa to 250 kPa (no nozzle). Plot T (ordinate vs. –A (abscissa). Also plot P (ordinate) vs. –A (abscissa) and V (ordinate) vs. –A (abscissa). For both of these plots, using the negative of the cross-sectional area on the horizontal axis means that the inflow conditions to the nozzle will be to the left and the outflow conditions will be to the right, similar to the figure above for Problem 8.16.

Problem 8.17

Solve Problem 8.16 using EES or other software.

Problem 8.16

Air enters a converging nozzle at 10 m/s, 250 kPa, and 300 K. Assuming an adiabatic reversible process, find the outflow velocity and temperature when the nozzle exit pressure is 150 kPa. If the inflow nozzle area is 0.1 m², what is the area at the outflow of the nozzle?
