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.
