external_resistance_to_water_vapor_transfer {TrenchR}

External Resistance to Water Vapor Transfer

Description

The function estimate external resistance to water vapor transfer using the Lewis rule relating heat and mass transport (Spotila et al. 1992)

Usage

external_resistance_to_water_vapor_transfer(H, ecp = 12000)

Arguments

H

numeric heat transfer (convection) coefficient (W m^-2 K^-1).

ecp

numeric aggregate parameter (J m^-3 K^-1) that is the product of the density of air (kg m^-3) and the specific heat of air at constant pressure (J kg^-1 K^-1). Default of 12000 (J m^-3 K^-1) commonly assumed.

Value

numeric external resistance to water vapor transfer (s m^-1).
