  2. Impact pressure - Wikipedia

    en.wikipedia.org/wiki/Impact_pressure

    In compressible fluid dynamics, impact pressure (dynamic pressure) is the difference between total pressure (also known as pitot pressure or stagnation pressure) and static pressure. [ 1 ] [ 2 ] In aerodynamics notation, this quantity is denoted as q c {\displaystyle q_{c}} or Q c {\displaystyle Q_{c}} .

  3. Dynamic pressure - Wikipedia

    en.wikipedia.org/wiki/Dynamic_pressure

    Dynamic pressure is one of the terms of Bernoulli's equation, which can be derived from the conservation of energy for a fluid in motion. [1] At a stagnation point the dynamic pressure is equal to the difference between the stagnation pressure and the static pressure, so the dynamic pressure in a flow field can be measured at a stagnation point ...

  4. Equivalent airspeed - Wikipedia

    en.wikipedia.org/wiki/Equivalent_airspeed

    where a 0 is 1,225 km/h (661.45 kn) (the standard speed of sound at 15 °C), M is the Mach number, P is static pressure, and P 0 is standard sea level pressure (1013.25 hPa). Combining the above with the expression for Mach number gives EAS as a function of impact pressure and static pressure (valid for subsonic flow):

  5. Fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Fluid_dynamics

    The concept of pressure is central to the study of both fluid statics and fluid dynamics. A pressure can be identified for every point in a body of fluid, regardless of whether the fluid is in motion or not. Pressure can be measured using an aneroid, Bourdon tube, mercury column, or various other methods.

  6. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    q = ⁠ 1 / 2 ⁠ ρv 2 is dynamic pressure, h = z + ⁠ p / ρg ⁠ is the piezometric head or hydraulic head (the sum of the elevation z and the pressure head) [11] [12] and; p 0 = p + q is the stagnation pressure (the sum of the static pressure p and dynamic pressure q). [13] The constant in the Bernoulli equation can be normalized.

  8. Max q - Wikipedia

    en.wikipedia.org/wiki/Max_q

    Chart of dynamic pressure during the Mercury-Redstone 4 mission. Max q occurs 90 seconds after launch, at 600 lb/sq ft (290 hPa).. The max q, or maximum dynamic pressure, condition is the point when an aerospace vehicle's atmospheric flight reaches the maximum difference between the fluid dynamics total pressure and the ambient static pressure.
