Air having a density of 1.27 kg/m³ enters the inlet of an engine at a rate of 1000 m³/sec of a circular cross
section of diameter 4 meters. If the bypass area is equivalent to 20% of inlet area due which the bypass
flow velocity is 20% compared to the core engine velocity. The bypass air and core air combine to pass
through the nozzle having an diameter of 1.5 meters then determine the following:
a. Core engine exit velocity.
b. Nozzle exit velocity.
c. Nozzle exit mass flow rate without thrust reverser deployed.
d.
Thrust reverser forces in x and y direction when the air is deflected equally at an angle of 45°
degrees due the thrust reverser.
