Static pressure and dynamic pressure are likely to vary significantly throughout the fluid but total pressure is constant along each streamline.
32.
The stream's static pressure tends to decrease, which creates a pressure difference between the wall and areas far from the wall.
33.
Gracey then refers to the air pressure at any point close to the aircraft as the " local static pressure ".
34.
These units consist of a computer controlled generator with additional sensors to correct for humidity, temperature, battery voltage and static pressure.
35.
The ball is then " sucked " from the region of high static pressure towards the region of low static pressure.
36.
This kinetic energy is then converted to an increase in potential energy / static pressure by slowing the flow through a diffuser.
37.
In unpressurised aircraft, the alternate static source is usually achieved by opening the static pressure system to the air in the cabin.
38.
Many authors describe the atmospheric pressure at the altitude at which the aircraft is flying as the " freestream static pressure ".
39.
The static pressure inside the chamber was used to control the degree of collapse of the tube, so providing a variable resistor.
40.
To avoid this problem, most aircraft intended for use in instrument meteorological conditions are equipped with an alternate source of static pressure.
