Extracted text: Assignment brief Task 1: Incompressible flow In the nozzle section of a wind tunnel sħown in Figure 1, the throat to the inlet area ratio is 0.06. The tunnel is turned on, and the pressure difference between the inlet (the settling chamber) and the test section is read as a height difference of 54 mm on a U-tube water manometer. The pressure and temperature of the airflow in the settling chamber (section 1) are 9.66 x 10* N/m² and 285.56 K, respectively. a) Calculate the temperature and pressure of the airflow in the test section (section 2) b) Calculate the velocity and Mach number of the airflow in the test section. c) If the exit to the throat area ratio is 12, calculate the velocity, pressure, and Mach number of the airflow in the exit section.
