The jet plane is flying upward such that its wings make an angle of attack of 15° with the horizontal. The plane is traveling at V = 750 m/s, in air having a temperature of 8°C and absolute pressure of 95 kPa. The leading edge of the wing has an angle of 8°.

Air at a temperature of 25° C and standard atmospheric pressure of 101.3 kPa flows through the nozzle into the pipe where the absolute internal pressure is 90 kPa. The nozzle has a throat diameter of d = 25 mm. Gas constant for air is R = 286.9 J/[kg K] and its specific heat ratio is k = 1.40. (Figure 1) Part A Determine the mass flow into the pipe.
