Extracted text: Q.1 An airstream with Mach number of 2, a pressure of 150 kPa and a temperature of 350 K enters a diverging channel as shown in the figure. If the ratio of the exit cross-sectional area to the inlet cross-sectional area is 3, determine the back pressure which is necessary to produce a normal shock wave in the channel with a cross- sectional area equal to twice the inlet cross-sectional area. Assume steady, one- dimensional and isentropic flow except through the normal shock wave. P; = 150KPA T; = 350K M = 2 A1 = A2 = 2A; A= 3A; (2)
