Tiivistelmä	Psychrometric analysis is the study of humid air (air-water vapor mixtures) and its properties. It is essential for designing and analyzing air conditioning, ventilation, and dehumidification systems. Psychrometric analysis relates dry-bulb temperature, wet-bulb temperature, dew point, relative humidity, and specific humidity through carefully constructed charts and correlations.	The Boussinesq Approximation simplifies the governing equations for natural convection by treating density as constant except in the buoyancy term. This approximation is valid when temperature variations produce small density changes and allows researchers to solve coupled heat-fluid flow problems without solving the full, nonlinear compressibility equations. The Boussinesq Approximation is fundamental to analyzing buoyancy-driven flows in buildings, enclosures, and geophysical applications.	The Stefan-Maxwell diffusion equation describes how multiple chemical species diffuse through each other in a mixture, accounting for interactions between all species pairs. Unlike Fick's law, which assumes species diffuse independently, Stefan-Maxwell theory captures the coupling that occurs when species with different diffusivities move at different rates. This is essential for analyzing gas separation, combustion, catalytic processes, and reactive distillation.
