## 1. Installation
**J**a**S**ali is part of the [ASALI](https://github.com/srebughini/JASALI) project and it is a **JavaScript** library to estimate **thermodynamic** and **transport** properties of **gas mixtures**.
Its [npm package](https://www.npmjs.com/package/jasali) can be installed as follow:
```
npm i jasali
```
## 2. Examples - JaSali is based on [International System of Units](https://en.wikipedia.org/wiki/International_System_of_Units)
**J**a**S**ali allows the estimation of thermodynamic and trasport properties of **pure gas species** and **gas mixtures**, as shown in the following examples.
### 2.1 Pure gas specie: O2
```javascript
import {
GasState,
GasSpecie
} from "jasali"
//Generate gas state object
let state = GasState({
temperature: 393.15,
pressure: 4e05
})
//Generate specie object
let specie = GasSpecie({
name: "O2",
gasState: state
})
//Extract properties from the specie object
let name = specie.getName()
let molecularWeight = specie.getMolecularWeight()
let viscosity = specie.getViscosity()
```
### 2.2 Gas mixture: AIR
```javascript
import {
GasState,
GasMixture
} from "jasali"
//Generate gas state object
let state = GasState({
temperature: 298.15,
pressure: 101325
})
//Generate mixture object
let mixture = GasMixture({
mixtureComposition: {
"O2": 0.21,
"N2": 0.78,
"AR": 0.01
},
gasState: state,
compositionType: "mole"
})
//Extract properties from the mixture object
let density = mixture.getDensity()
let molecularWeight = mixture.getMolecularWeight()
let viscosity = mixture.getViscosity()
```
### 2.3 Gas mixture: Chemical equilibrium at constant temperature and pressure
```javascript
import {
GasState,
GasMixture
} from "jasali"
//Generate gas state object
let state = GasState({
temperature: 3000,
pressure: 4e05
})
//Generate mixture object
let mixture = GasMixture({
mixtureComposition: {
"CO": 0.1,
"CO2": 0.2,
"O2": 0.7
},
gasState: state,
compositionType: "mole"
})
//Extract chemical equilibrium composition
let x = mixture.calculateChemicalEquilibriumTP()
```
### 2.4 HTML frontend
