impact pressure การใช้

• Likewise, the calibrated airspeed is a function of the compressible impact pressure.
• Compressibility error arises because the impact pressure will cause the air to compress in the pitot tube.
• When input to an airspeed indicator, impact pressure is used to provide a calibrated airspeed reading.
• For example, a combination of the thermal Doppler broadening and the impact pressure broadening yields a Voigt profile.
• Since the airspeed indicator capsule responds to impact pressure, CAS is defined as a function of impact pressure alone.
• Since the airspeed indicator capsule responds to impact pressure, CAS is defined as a function of impact pressure alone.
• The Minkin breakthrough used the force of hydraulic impact pressure to significantly improve the cleaning power of the aqueous parts washer.
• Electronic Flight Instrument Systems ( EFIS ) contain an air data computer with inputs of impact pressure, static pressure and total air temperature.
• Using a DC pulse as the electric current, spark plasma, spark impact pressure, joule heating, and an electrical field diffusion effect would be created.
• These formulae can then be used to calibrate an airspeed indicator when impact pressure ( q _ c ) is measured using a water manometer or accurate pressure gauge.
• Combining the above with the expression for Mach number gives an expression for TAS as a function of impact pressure, static pressure and static air temperature ( valid for subsonic flow ):
• Some authors in the field of compressible flows use the term " dynamic pressure " or " compressible dynamic pressure " instead of " impact pressure ".
• :To counter the impact of any projectile, you want to spread the force out over as large of an area as possible to reduce the impact pressure and you also want to spread the impact out over as long of a time period as possible.
