Total pressure

  • Total Pressure
  • In an MHD fluid it is the number density (N) times Boltzmann constant times the temperature in Kelvin.
Abstract from DBPedia
    In physics, the term total pressure may indicate two different quantities, both having the dimensions of a pressure: * In fluid dynamics, total pressure () refers to the sum of static pressure p, dynamic pressure q, and gravitational head, as expressed by Bernoulli's principle: where ρ is the density of the fluid, g is the local acceleration due to gravity, and z is the height above a datum.If the variation in height above the datum is zero, or so small it can be ignored, the above equation reduces to the following simplified form: * In a mixture of ideal gases, total pressure refers to the sum of each gas' partial pressure.
