Flow Properties of Horizontal Rectangular Channel Hydraulic Jumps



    
Flow Rate Q (m3 s-1)

Channel Width B (m)

Upstream Depth h1 (m)

Downstream Depth h2 (m)

Depth Ratio h2/h1

Upstream Velocity v1 (m s-1)

Downstream Velocity v2 (m s-1)

Velocity Ratio v1/v2



Upstream Froude Number Fr1

Downstream Froude Number Fr2

Froude Number Ratio Fr1/Fr2

Fr1 < 1.0 : Subcritical Flow
Fr1 = 1.0 : Critical Flow
1.0 < Fr1 < 1.7 : Supercritical Flow, Undular Jump
1.7 < Fr1 < 2.5 : Supercritical Flow, Weak Jump
2.5 < Fr1 < 4.5 : Supercritical Flow, Oscillating Jump
4.5 < Fr1 < 9.0 : Supercritical Flow, Steady Jump
Fr1 > 9.0 : Supercritical Flow, Strong Jump
===================================================
Fr2 < 1.0 : Subcritical Flow
Fr2 = 1.0 : Critical Flow
1.0 < Fr2 < 1.7 : Supercritical Flow, Undular Jump
1.7 < Fr2 < 2.5 : Supercritical Flow, Weak Jump
2.5 < Fr2 < 4.5 : Supercritical Flow, Oscillating Jump
4.5 < Fr2 < 9.0 : Supercritical Flow, Steady Jump
Fr2 > 9.0 : Supercritical Flow, Strong Jump
