# Psychrometry library for Rust

## Functions to calculate thermodynamic properties of gas-vapor mixtures

Psychrometry is derived from PsychroLib <https://github.com/psychrometrics/psychrolib>.

This library should make it easy to integrate temperature and humidity sensors with
your rust based dashboards. Versions of PsychroLib for other languages are available
from the above repository. The names are as close to the original as possible. The one
major difference is that the function calls in this library is in snake_case while the original
repository uses CamelCase. This library will update when it merges upstream.

## Quick Start

The following example lets you get the enthalpy of moist air with dry bulb temperature
and relative humidty.
```
use psychrometry::psychrolib::*;
use psychrometry::quantities::{Pressure, SpecificEnthalpy, Temperature};
use psychrometry::units::{Atmosphere, Fahrenheit, JoulesPerKg, KilojoulesPerKg};
let rel_hum = 0.25;
let tdry_bulb = Temperature::<Fahrenheit>::from(86);
let pres_ambient = Pressure::<Atmosphere>::from(1);
let sp_enthalpy: SpecificEnthalpy<KilojoulesPerKg> =
    get_moist_air_enthalpy_from_rel_hum(tdry_bulb, rel_hum, pres_ambient).unwrap();
let sp_enthalpy_exp = SpecificEnthalpy::<JoulesPerKg>::from(47015.61);
assert_eq!(sp_enthalpy_exp, sp_enthalpy);
```
