Open Channel Flow Gradually Varied Flow
|
Example: Consider flow
along the horizontal channel past a sluice gate as shown in the figure below. Let
L be of the order of y1. Strategy: Apply the energy equation and use specific
energy plot to interpret results. y1 + V12/2g =
y2 + V22/2g + ( Sf – So
) L |
|
Case 1: Neglect energy loss ( Sf – So ) L. q = flow rate per unit width of channel What
size gate do you need for the same flowrate,
q? Look at specific energy plot. Result: y2 < y1 |
