QUESTION:

As shown in Fig. P4.37, air enters the diffuser of a jet engine operating at steady state at \(18 \mathrm{kPa}, 216 \mathrm{~K}\) and a velocity of \(265 \mathrm{~m} / \mathrm{s}\), all data corresponding to high-altitude flight. The air flows adiabatically through the diffuser and achieves a temperature of \(250 \mathrm{~K}\) at the diffuser exit. Using the ideal gas model for air, determine the velocity of the air at the diffuser exit, in \(\mathrm{m} / \mathrm{s}\).
