Calculates a variety of air thermodynamic properties from the measured temperature, pressure, and humidity.

Variables able to calculated:
rho - [kg m^-3] - Density
mu - [N s m^-2] - Dynamic viscosity
k - [W m^-1 K^-1] - Thermal conductivity
c_p - [J kg^-1 K^-1] - Specific heat capacity (constant pressure)
c_v - [J kg^-1 K^-1] - Specific heat capacity (constant volume)
gamma - [1] - Ratio of specific heats
c - [m s^-1] - Speed of sound: c = (gamma*R*T/M)^0.5
nu - [m^2 s^-1] - Kinematic viscosity: nu = mu/rho
alpha - [m^2 s^-1] - Thermal diffusivity: alpha = k/(rho*c_p)
Pr - [1] - Prandtl number: Pr = mu*c_p/k
M - [kg mol^-1] - Molar mass of humid air
R - [J kg^-1 K^-1] - Specific gas constant
h - [%] - Relative humidity (if dew point inputted)

Calculations are based around atmospheric temperatures and pressures, i.e. not for the use of high temperature combustion. See references for details and limitations.
