Abstract
The reference wind velocity inside the test section of an open-type subsonic wind tunnel is established from the measurements of dynamic pressure and the average static wall pressure difference between stations at upstream of the test section and at the settling chamber. A wind tunnel calibration factor was obtained which relates the dynamic pressure and thus the wind velocity inside the test section with the average static wall pressure difference at a station near upstream of the test section and at the settling chamber. An average wind tunnel calibration factor was found to be 0.8189. The longitudinal variation of static pressure inside the test section is also obtained using the pitot-static tube.
