## Unit safety

All calculations of thermophysical properties are **_unit safe_** (thanks to
[UnitsNet](https://github.com/angularsen/UnitsNet)). This allows you to avoid errors associated
with incorrect dimensions of quantities, and will help you save a lot of time on their search
and elimination. In addition, you will be able to convert all values to many other dimensions
without the slightest difficulty.

## Project structure

- `Fluid` class - an implementation of pure fluids and binary mixtures (`IFluid` interface)
- `Mixture` class - an implementation of mixtures with pure fluids components (`IMixture` interface)

using UnitsNet.NumberExtensions.NumberToPressure;
using UnitsNet.Units;

var waterVapour = new Fluid(FluidsList.Water).DewPointAt(1.Atmospheres());
Console.WriteLine(waterVapour.SpecificHeat.JoulesPerKilogramKelvin);          // 2079.937085633241
Console.WriteLine(waterVapour.SpecificHeat);                                  // 2.08 kJ/kg·K
Console.WriteLine(
    waterVapour.SpecificHeat.ToUnit(SpecificEntropyUnit.CaloriePerGramKelvin) // 0.5 cal/g·K
);
```

### Incompressible binary mixtures

with _60 %_ mass fraction at _100 kPa_ and _-20 °C_:

```csharp
using SharpProp;
using UnitsNet.NumberExtensions.NumberToPressure;
using UnitsNet.NumberExtensions.NumberToRatio;
using UnitsNet.NumberExtensions.NumberToTemperature;
using UnitsNet.Units;

var propyleneGlycol = new Fluid(FluidsList.MPG, 60.Percent()).WithState(
    Input.Pressure(100.Kilopascals()),
    Input.Temperature((-20).DegreesCelsius())
);
Console.WriteLine(propyleneGlycol.DynamicViscosity?.PascalSeconds);      // 0.13907391053938878
Console.WriteLine(propyleneGlycol.DynamicViscosity);                     // 139.07 mPa·s
Console.WriteLine(
    propyleneGlycol.DynamicViscosity?.ToUnit(DynamicViscosityUnit.Poise) // 1.39 P
);
```

### Mixtures

To calculate the density of ethanol aqueous solution (with ethanol _40 %_ mass fraction)
at _200 kPa_ and _277.15 K_:

```csharp
using SharpProp;
using UnitsNet;
using UnitsNet.NumberExtensions.NumberToPressure;
using UnitsNet.NumberExtensions.NumberToRatio;
using UnitsNet.NumberExtensions.NumberToTemperature;
using UnitsNet.Units;

var mixture = new Mixture(
    new List<FluidsList> { FluidsList.Water, FluidsList.Ethanol },
    new List<Ratio> { 60.Percent(), 40.Percent() }
).WithState(
    Input.Pressure(200.Kilopascals()),
    Input.Temperature(277.15.Kelvins())
);
Console.WriteLine(mixture.Density.KilogramsPerCubicMeter);               // 883.3922771627759
Console.WriteLine(mixture.Density);                                      // 883.39 kg/m3
Console.WriteLine(mixture.Density.ToUnit(DensityUnit.GramPerDeciliter)); // 88.34 g/dl
```

### Humid air

To calculate the wet bulb temperature of humid air
at _300 m_ above sea level, _30 °C_ and _50 %_ relative humidity:

```csharp
using SharpProp;
using UnitsNet.NumberExtensions.NumberToLength;
using UnitsNet.NumberExtensions.NumberToRelativeHumidity;
using UnitsNet.NumberExtensions.NumberToTemperature;
using UnitsNet.Units;

var humidAir = new HumidAir().WithState(
    InputHumidAir.Altitude(300.Meters()),
    InputHumidAir.Temperature(30.DegreesCelsius()),
    InputHumidAir.RelativeHumidity(50.Percent())
);
Console.WriteLine(humidAir.WetBulbTemperature.Kelvins);                  // 295.06756903366403
Console.WriteLine(humidAir.WetBulbTemperature);                          // 21.92 °C
Console.WriteLine(
    humidAir.WetBulbTemperature.ToUnit(TemperatureUnit.DegreeFahrenheit) // 71.45 °F
);
```

### Equality of instances

You can simply determine the equality of `Fluid`, `Mixture` and `HumidAir` instances by its state.
Just use the `Equals` method (**_not_** the equality operators: `==` and `!=`).
Exactly the same way you can compare inputs (`Input`, `InputHumidAir` or any `IKeyedInput` record).

For example:

```csharp
using SharpProp;
using UnitsNet.NumberExtensions.NumberToPressure;
using UnitsNet.NumberExtensions.NumberToRelativeHumidity;
using UnitsNet.NumberExtensions.NumberToTemperature;

var humidAir = new HumidAir().WithState(
    InputHumidAir.Pressure(1.Atmospheres()),
    InputHumidAir.Temperature(20.DegreesCelsius()),
    InputHumidAir.RelativeHumidity(50.Percent())
);
var sameHumidAir = new HumidAir().WithState(
    InputHumidAir.Pressure(101325.Pascals()),
    InputHumidAir.Temperature(293.15.Kelvins()),
    InputHumidAir.RelativeHumidity(50.Percent())
);
Console.WriteLine(humidAir.Equals(sameHumidAir)); // true
```

### Converting to a JSON string

The `Fluid`, `Mixture` and `HumidAir` classes have the `AsJson` method, which converts the instance
to a JSON string. For example, converting a `Fluid` instance to an _indented_ JSON string:

```csharp
using SharpProp;
using UnitsNet.NumberExtensions.NumberToTemperature;

var refrigerant = new Fluid(FluidsList.R32).DewPointAt(5.DegreesCelsius());
Console.WriteLine(refrigerant.AsJson());
```

As a result:

### Deep cloning

The `Fluid`, `Mixture` and `HumidAir` classes have the `Clone` method,
which performs a deep (full) copy of the instance:

```csharp
using SharpProp;
using UnitsNet.NumberExtensions.NumberToPressure;
using UnitsNet.NumberExtensions.NumberToTemperature;

var origin = new Fluid(FluidsList.Water).WithState(
    Input.Pressure(1.Atmospheres()),
    Input.Temperature(20.DegreesCelsius())
);
var clone = origin.Clone();
Console.WriteLine(origin.Equals(clone)); // true
clone.Update(
    Input.Pressure(1.Atmospheres()),
    Input.Temperature(30.DegreesCelsius())
);
Console.WriteLine(origin.Equals(clone)); // false
```
