Chemics

Added

- `cp_wood()` for wood heat capacity

Added

- `k_wood()` for wood thermal conductivity
- Test and documentation for `k_wood()` function

Fixed

- Fix display of the `atomic_elements` dictionary in documentation

Added
- `mu_graham()` to calculate viscosity of a gas mixture using mole fraction and viscosity of each component
- `mu_herning()` to calculate viscosity of a gas mixture using molecular weight, mole fraction, and viscosity of each component

Changed
- Renamed `molecular_weight()` function to `mw()`
- Input parameters for `mw_mix()` are now molecular weight and mole fraction of each gas component

Removed
- Deleted the `mu_gas_mix()` function. Use the `mu_graham()` function instead

Added
- Added option to plot min and max particle size on Geldart chart

Changed
- Renamed `plot_geldart` function to `geldart_chart`
- This function now returns a Matplotlib figure

Added
- `massfrac_to_molefrac()` to convert from mass fractions to mole fractions
- `molefrac_to_massfrac()` to convert from mole fractions to mass fractions
- Tests for the mass fraction and mole fraction functions

Fixed
- Correct docstring style for `slm_to_lpm()`

Added
- Geldart particle classification
