    online_standard_suppressed_rectangular: Discharge through a standard suppressed rectangular weir

Formula:

Q = 3.33 L H^3/2          [in U.S. Units]

Head H on the weir, in m [or ft]
Length L of the weir, in m [or ft]
Height P to the weir crest, in m [or ft]

Discharge Q in L/s [or cfs]
See USBR Manual for general methodology

INPUT DATA:       [Description]

Select Units:

Head H :


[ H > 0 ]

Length L :


[ L > 0 ]

Height P :


[ H > 0 ]

OUTPUT:

Warning: Ratio P/H = 0 < 2.

Warning: Ratio L/H = 0 ≤ 3.

Discharge Q : 0
