Math & Numbers
计算雷诺数 Re=ρ·v·D/μ（动力粘度模式）或 Re=v·D/ν（运动粘度模式，ν=μ/ρ），并按 Re<2300 层流、2300≤Re<4000 过渡、Re≥4000 湍流进行分类。直径支持 m/cm/mm，结果同时给出 ν=μ/ρ。用于管流与流体力学流态判断。
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/reynolds-number-calculator' \
-H 'Content-Type: application/json' \
-d '{"solveFor":"dynamic","density":1000,"velocity":2,"diameter":0.05,"diameterUnit":"m","dynamicViscosity":0.001,"kinematicViscosity":0,"decimalPlaces":4}'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/reynolds-number-calculator| 参数名 | 类型 | 必填 | 说明 |
|---|---|---|---|
| solveFor | select | 否 | Dynamic mode takes ρ, v, D, μ and also computes ν = μ/ρ. Kinematic mode takes v, D, ν directly. |
| density | number | 否 | Fluid density ρ (kg/m³). Required when Solve For = Dynamic. |
| velocity | number | 是 | Mean flow velocity v (m/s). |
| diameter | number | 是 | Characteristic length / hydraulic diameter D, in the selected Diameter Unit. |
| diameterUnit | select | 否 |
