Consider a low-speed subsonic wind tunnel with a nozzle contraction ratio of 1:20. One side of a mercury manometer is connected to the settling chamber and the other side to the test section. The pressure and temperature in the test section are 1 atm and 300 K, respectively. What is the height difference between the two columns of mercury when the test section velocity is 80 m/s?
