1. An open-ended tube probe is oriented at an angle of 30? with the flow direction in an airflow at 200 kPa and 50?C. The air velocity is 20 m/s. Calculate the pressure indicated by the probe.
2. A Pitot tube is exposed to the same flow stream as in Prob. 7.45 but is yawed at an angle of 8? with the flow direction. What static, dynamic, and stagnation pressures will be indicated by the probe? What error would result in the velocity determination if these values were assumed to be at a zero yaw angle?
Prob. 7.45
An open-ended tube probe is oriented at an angle of 30? with the flow direction in an airflow at 200 kPa and 50?C. The air velocity is 20 m/s. Calculate the pressure indicated by the probe.
3. An impact probe is exposed to an airflow stream at 0?C, 20 kPa, and 600 m/s. What pressure will be indicated by the probe at a zero yaw angle?
