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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「total pressure」の詳細全文を読む スポンサード リンク
