Reconsider Prob. 9–140. In the problem statement, replace the inlet mass flow rate with an inlet volume flow rate of 18.1 m³/s. Using appropriate software, investigate the effect of compressor inlet temperature in the range of –20 to 30°C on the force that must be applied to the brakes to hold the plane stationary. Plot this force as a function of compressor inlet temperature.

Data From Q#140:

Consider an aircraft powered by a turbojet engine  that has a pressure ratio of 9. The aircraft is stationary on the  ground, held in position by its brakes. The ambient air is at 7°C  and 95 kPa and enters the engine at a rate of 20 kg/s. The jet  fuel has a heating value of 42,700 kJ/kg, and it is burned completely  at a rate of 0.5 kg/s. Neglecting the effect of the diffuser  and disregarding the slight increase in mass at the engine exit  as well as the inefficiencies of engine components, determine  the force that must be applied on the brakes to hold the plane stationary.
