As shown in Fig., air enters the diffuser of a jet engine operating at steady state at 18 kPa, 216 Kand a velocity of 265 m/s, all data corresponding to high-altitude flight. The air flows adiabatically through the diffuser and achieves a temperature of 250 K at the diffuser exit. Using the ideal gas model for air, determine the velocity of the air at the diffuser exit, in m's.
