Compute discharge through an orifice.
请输入参数后计算。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Torricelli law | v = sqrt( 2 · g · H ), where H is the head above the orifice | Torricelli E. (1644), Opera Geometrica |
| Discharge | Q = mu · A · sqrt( 2 · g · H ), where mu is the discharge coefficient | Classical orifice hydraulics |
| Discharge coefficient of a sharp-edged orifice | For a sharp-edged small orifice the coefficient is about 0.60 to 0.62 | Classical orifice hydraulics |
| Large orifices | When the head varies over the orifice height, integrate over the opening | Chow VT, Open-Channel Hydraulics, orifice treatment |
