The Specific Energy
Diagram
|
In a Nut Shell: Use the
specific energy diagram to view transition during a hydraulic jump. Recall
the definition of specific energy is E
= y + V2 / 2g = y + q2/ 2gy2 The plot of This
function results in the specific energy diagram as shown below. |
|
Note the loss of energy, hL , (energy
dissipated over jump). y2 = depth of water after jump y1 = depth of water before jump yc = critical depth of water q = flow rate per unit width Note
further that q = constant |
