A type of current meter created in 1728 by the French physicist Henri Pitot (1695-1771). When an object is placed in a flow with a velocity of v , a point where the flow velocity is zero is created, and this point is called a stagnation point. According to Bernoulli's theorem, for a fluid with constant density, the pressure p0 at the stagnation point is expressed as follows, where ρ is the density: [Ryo Ikeuchi] [Reference] | | | | |©Shogakukan "> Principle of the Pitot Tube Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
フランスのピトーHenri Pitot(1695―1771)によって1728年につくられた流速計の一種。速さvの流れの中に物体を置くと、流速がゼロの点ができ、その点をよどみ点という。ベルヌーイの定理によれば、密度変化をしない流体では、よどみ点の圧力p0は、密度をρとすると、 [池内 了] [参照項目] | | | | |©Shogakukan"> ピトー管の原理 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
