A divergent duct as shown in Figure Q8 is secured by a strut that keeps the duct stationary. Air flows through the duct in the direction of the arrow at a rate of 40 kg/s. It enters the duct at a velocity of 700 m/s and a static pressure of 15 kPa and leaves the duct at a velocity of 80 m/s and a static pressure of 300 kPa. The inlet area is 0.24m and the exit area is 0.3m. The ambient pressure is 15 kPa. Calculate the magnitude of the force on the strut and give the direction of that force relative to the direction of flow.
