#summary Hamopy function library

=Library of functions=

All material-independant values, universal constants and state equations are stored within the hamopy\ham_library file. In addition to constant properties such as the latent heat of evaporation, the universal gas constant and the thermal conductivity of air, the file includes 5 useful methods: || p_sat(T) || Water vapor saturation pressure (Pa) || || D_va(T) || Water vapor diffusivity in air (m^2^/s) || || p_v(p_c, T) || Water vapor pressure (Pa) || || HR(p_c, T) || Relative humidity || || p_c(HR, T) || Capillary pressure (Pa) ||

The last three methods are equivalent formulations of the Clausius-Clapeyron equation. It is used to calculate the relative humidity from values of the capillary pressure, and inversely.

Here is an example of use: {{{ from hamopy import ham_library as ham

ham.cp_liq ham.p_sat(280) ham.p_c(0.92, 299) }}} This script first returns the value of the liquid water specific heat, then the water vapor saturation pressure at 280 K, then the capillary pressure at 92 %RH and 299 K.
