How do you calculate? Explain. |

I also got 9.334. y2/y1 = 1/2*(√(1+8.F1^2) - 1) y1 = depth of water before hydraulic jump y2 = depth of water after hydraulic jump F1 = froude number of flow before hydraulic jump i.e F=V/√(g*depth) = 13.72/(√(9.81*3)) = 2.52. y2 = 3* [1/2*( sqrt(1+8*2.52^2) - 1)]. y2 = 9.334m. |
