In a subsonic wind tunnel, one side of a mercury manometer is connected to the settling chamber and the other side is connected to the test section. The contraction ratio of the nozzle A2/A equals 1:16. The pressure and temperature in the settling chamber are P = 1.12 bar and T = 30C, respectively. When the tunnel is running, the height difference between the two columns of mercury is 12 cm. The density of liquid mercury is 1.36 * 104. y=1.4, and R = 287 J/kg. K. Calculate: (i) The pressure difference between the two columns. kg m3' (ii) The density of the fluid in the wind tunnel. (iii) The airflow velocity in the test section. (iv) The Mach number in the test section. 7 marks 4 marks 5 marks 4 marks In a subsonic wind tunnel, one side of a mercury manometer is connected to the settling chamber and the other side is connected to the test section.
