Hydraulic Jump Lab
Explore how tailwater sets the position of a hydraulic jump while the local Froude number determines which jump type forms.
About this model
Scientific basis
\[
Fr_1=\frac{V_1}{\sqrt{g y_1}},\qquad
\frac{y_2}{y_1}=\frac{1}{2}\left(\sqrt{1+8Fr_1^2}-1\right)
\]
\[
\frac{dy}{dx}=-\frac{S_f}{1-Fr^2},\qquad
S_f=\frac{n^2 q^2}{y^{10/3}}
\]
\[
P_B=C_D\,\rho\,\frac{V_B^2 h}{2}
