Question: Consider a low - speed subsonic wind tunnel with a 1 2 / 1 contraction ratio for the nozzle. If the flow in the test

Consider a low-speed subsonic wind tunnel with a 12/1 contraction ratio for the nozzle. If the flow in the test section is at standard sea level conditions with a velocity of 60 m/s, calculate the height difference in a U-tube mercury manometer with one side connected to the nozzle inlet and the other to the test section. Assume that the density of liquid mercury is 1.36104 kg/m3 and acceleration due to gravity, g=9.81 m/s2.
