latent_heat_H2O {aiRthermo}

Latent heat of vaporization or sublimation of water

Description

This function calculates the latent heat of vaporization or sublimation of water depending as a function of temperature. It uses a polynomial approximation over water or ice.

Usage

latent_heat_H2O(Temps)

Arguments

Temps

A vector with temperature values (K).

Details

Taking into account the observed values in tables from Rogers and Yau (1989) and Feistel and Wagner (2006), a polynomial model is used to calculate the latent heat at different temperatures.

Value

This function returns the latent heat of vaporization or sublimation of water.
