dot-get_re: Re: Reynolds number

In muir-lab/tleavesMC: Schymanski Equation

Description

Re: Reynolds number

Usage

.get_re(T_leaf, pars, unitless)

Arguments

T_leaf	Leaf temperature in Kelvin
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

Re = u d / D_m

Symbol	R	Description	Units	Default
d	leafsize	Leaf characteristic dimension in meters	m	0.1
D_m	D_m	diffusion coefficient of momentum in air	m^2 / s	calculated
u	wind	windspeed	m / s	2

Value

A unitless number of class units

Examples

library(tealeaves)

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

T_leaf <- set_units(298.15, K)

tealeaves:::.get_re(T_leaf, c(cs, ep, lp), FALSE)
