dot-get_gbw: g_bw: Boundary layer conductance to water vapour (m / s)

In cdmuir/tealeaves: Solve for Leaf Temperature Using Energy Balance

g_bw: Boundary layer conductance to water vapour (m / s)

Description

g_bw: Boundary layer conductance to water vapour (m / s)

Usage

.get_gbw(T_leaf, surface, pars, unitless)

Arguments

T_leaf	Leaf temperature in Kelvin
surface	Leaf surface (lower or upper)
pars	Concatenated parameters (leaf_par, enviro_par, and constants)
unitless	Logical. Should function use parameters with units? The function is faster when FALSE, but input must be in correct units or else results will be incorrect without any warning.

Details

g_\mathrm{bw} = D_\mathrm{w} Sh / d

Symbol	R	Description	Units	Default
d	leafsize	Leaf characteristic dimension in meters	m	0.1
D_\mathrm{w}	D_w	diffusion coefficient for water vapour	m^2 / s	calculated
Sh	Sh	Sherwood number	none	calculated

Value

Value in m / s of class units

Examples

library(tealeaves)

cs <- make_constants()
ep <- make_enviropar()
lp <- make_leafpar()

T_leaf <- set_units(298.15, K)

tealeaves:::.get_gbw(T_leaf, "lower", c(cs, ep, lp), FALSE)
