Math & Numbers
计算薄壁锐缘堰的流量。矩形堰（无侧收缩）Q=(2/3)·C_d·√(2g)·b·H^1.5；V 型（三角）堰 Q=(8/15)·C_d·√(2g)·tan(θ/2)·H^2.5。其中 b 为堰宽、H 为堰上水头、θ 为 V 型堰顶角。流量系数 C_d 留空时：矩形堰取 0.611（Rehbock/Francis 简化典型值），V 型堰取 0.58。堰宽支持 m/cm，水头支持 m/cm/mm，结果同时给出 m³/s、L/s、L/min、m³/h 四种单位。

POST https://api.elysiatools.com/zh/api/tools/weir-flow-calculator| 参数名 | 类型 | 必填 | 说明 |
|---|---|---|---|
| weirType | select | 否 | Rectangular (suppressed, no side contraction) takes crest width b and head H. V-Notch (triangular) takes notch angle θ and head H. |
| crestWidth | number | 是 | Crest width b of the rectangular weir. Enter in the selected Crest Width Unit. Required when Weir Type = Rectangular. |
| crestWidthUnit | select | 否 | — |
| notchAngle | number | 否 | V-notch angle θ in degrees (0 < θ ≤ 180). Required when Weir Type = V-Notch. |
| head | number | 是 |
