# sp-gas
Calc gas range
## Install
``` node
npm i sp-gas //or yarn add sp-gas
```
## CDN
``` js
let { calcGasRadius } = __Gas
```
### Usage
``` js
let { calcGasRadius } = require("sp-gas")
let speed = 0 // 泄漏风速
let radius = 0 // 泄漏开口半径
let p1 = 3.17 //临界压力
let p2 = 1393 //两相混合物的平均密度
let cp = 0.957 //两相混合物比定压热容
let t = 24.85 //两相混合物温度
let t0 = -34.15 //液体沸点温度
let h = 280 //液体汽化热
let c0 = 890 // 死亡浓度
let c1 = 300 // 重伤浓度
let c2 = 90 // 轻伤浓度
let c3 = 9 // 反应浓度
let r0 = calcGasRadius(speed, c0, radius,p1, p2, cp, t, t0, h) // 致死半径
let r1 = calcGasRadius(speed, c1, radius,p1, p2, cp, t, t0, h) // 重伤半径
let r2 = calcGasRadius(speed, c2, radius,p1, p2, cp, t, t0, h) // 轻伤半径
let r3 = calcGasRadius(speed, c3, radius,p1, p2, cp, t, t0, h) // 警戒半径
```
