pitot-static tube

A combination tube used in a pitot-static system, located on the fuselage of the aircraft. It measures the total, or ram, pressure, as well as static pressure. The ram pressure is used for the ASI (air-speed indicator) and the Mach meter. The static system is used for the altimeter and the vertical speed indicator. It consists of a pitot head, which measures the total pressure of the airflow. Vents or small holes on the side of the tube are used to pick up static pressure. See pitot pressure.

Likewise standard spiral duct pressure loss data obtained using either Pitot-static tubes or wall static pressure taps with piezometer rings are depicted in Figure 6.
In one instance the pressure loss was measured using Pitot-static tubes mounted at the duct centerline, at axial locations prescribed by ASHRAE Standard 120.
For cases where an internal support frame was absent the absolute roughness of the ducts based on test data obtained using Pitot-static tubes was 0.
