Math & Numbers
由风量 Q 与设计流速 v 求风管截面尺寸：截面积 A=Q/v。圆形风管直径 D=√(4A/π)；矩形风管给定长宽比 r=a/b，则 b=√(A/r)，a=r·b，并按 ASHRAE 给出等效直径 D_eq=1.30·(a·b)^0.625/(a+b)^0.25。风量支持 m³/s/m³/h/CFM，结果同时给出 mm 与英寸。
用三种语言从你的代码中调用此工具。
curl -X POST 'https://api.elysiatools.com/zh/api/tools/duct-size-calculator' \
-H 'Content-Type: application/json' \
-d '{"shape":"rectangular","flowRate":1000,"flowUnit":"m3/h","velocity":4,"aspectRatio":2,"decimalPlaces":2}'以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。
POST https://api.elysiatools.com/zh/api/tools/duct-size-calculator| 参数名 | 类型 | 必填 | 说明 |
|---|---|---|---|
| shape | select | 否 | Duct cross-section shape: Rectangular or Circular. |
| flowRate | number | 是 | Volumetric air flow rate Q. Enter in the selected Flow Unit. |
| flowUnit | select | 否 | — |
| velocity | number | 是 | Design mean air velocity v in m/s. Typical: low-pressure 3–5 m/s, main 6–8 m/s. |
| aspectRatio | number | 否 | Rectangular duct aspect ratio r = a/b (long side over short side). Used only when Duct Shape = Rectangular. Typical 1–4. Default 2. |
