how to calculate hydraulic jump. Derivation of formula for simple momentum conserving hydraulic jump in rectangular channel. For a hydraulic jump to occur the pre jump Froude number F r1 should be greater than 1.
479 indicate that jump length is typically 4y 2 to 6y 2. The sum of forces is equal to the momentum change. Experiments are required French 1985 p.
Or m for SI.
479 indicate that jump length is typically 4y 2 to 6y 2. E2 the sequent downstream head in ft for US. Q the flow rate through the hydraulic jump in cfs for US. Y2 depth of flow after the hydraulic jump ft.
