Froude number hydraulic jump
WebNow, depth of hydraulic jump = (d 2-d 1) Froude number on the upstream side is given by Substituting the value in equation (12.7) we get, 12.2 Energy Dissipation due to Hydraulic Jump . When hydraulic jump take place, a loss of energy due to eddies formation and turbulence occurs. WebMar 17, 2024 · 60) that there is no hydraulic jump for Froude number between 1 and 1.7 and only a weak one for Froude number between 1.7 and 2.5. He adds that the energy loss is negligible for the first one and weak for the second one. As $\textit{Fr} =\sqrt(3)\simeq 1.7$, this equation may not be relevant in this case to evaluate the energy loss. Also the ...
