Physics:Blasius–Chaplygin formula
From HandWiki
The Blasius–Chaplygin formula, devised by Sergey Chaplygin from the work of Heinrich Blasius relates the force [math]\displaystyle{ \bar{L} }[/math] given by a complex velocity field [math]\displaystyle{ f }[/math]
[math]\displaystyle{ \bar{L}=\frac{I\rho}2\int_\gamma f^2(z)\,\mathrm dz }[/math]
The equation stated above appears from the analysis of the velocity over a body with a boundary [math]\displaystyle{ \gamma }[/math], taking Bernoulli's law into consideration.[1]
