Air with a velocity of 150 m/s enters a nozzle at a pressure of 200 kPa and temperature of 77 °C. Under the assumption of isentropic flow, calculate the temperature and pressure of the air at the location where velocity is equal to the acoustic sound. Determine the ratio of the area at the location to that of the entrance area and the percent change in velocity.
