This paper is a re-examination of the gross thrust uncertainty contribution of two inlet static pressure assessment methods. The first method is direct measurement near the labyrinth seal, station 1.0, which is the connection between the inlet duct and the bellmouth. The second method is to ...
A duct size calculator, commonly known as a ductulator, depends on factors like the size of the space you’re heating or cooling, air flow velocity, friction loss, and available static pressure of the HVAC system.
Pressure distribution across the height of the channel and across the width of the channel was obtained. The magnitude of the cross-flow velocities in the channel were determined and mapped. It was found that the data for various rotational speeds could be collapsed upon a single curve by ...
PURPOSE: A pressure measurement device is provided to improve the reliability of measured pressure information and to simplify the structure of a product by detecting pressure through a pressure sensor after averaging inside a pressure gathering cover. CONSTITUTION: Plural detection holes(2) are formed...
The paper presents the results of measurement of the static pressure, total pressure and swirl in the flow through an S-shaped duct of typical air intake proportions mounted in a wind tunnel and tested at different incidences and different through-flow ratios. In order to reduce the magnitude ...
Connect the total pressure tube to the 922 "+" port, and connect the static pressure tube to the "-" port. Select "Flow Volume" mode Select either round or rectangular duct Enter inside duct dimensions as prompted Zero meter Position the Pitot-Static tube tip within the duct at the first...
These lengths are taken from the hypotenuse of right-angled triangles whose height is equal to the height of the front elevation, and the base measurement is taken from the projected lengths in the plan view. Note that the lengths A2 and A3 are the same, as are A1 and A4, since the ...

Metastability-engineering, e.g., transformation-induced plasticity (TRIP), can enhance the ductility of alloys, however it often comes at the expense of relatively low yield strength. Here, using a metastable Ti-1Al-8.5Mo-2.8Cr-2.7Zr (wt.%) alloy as a mo
