Ar

Ar: Archimedes number

Description

Ar: Archimedes number

Usage

Ar(T_leaf, pars, unitless = FALSE)

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

The Archimedes number is a dimensionless number that describes when free or forced convection dominates.

Ar = Gr / Re ^ 2


Symbol R Description Units Default
Gr Gr Grashof number none calculated
Re Re Reynolds number none calculated

Value

unitless = TRUE: A unitless number of class numeric unitless = FALSE: A unitless number of class units Also returns Reynolds and Grashof numbers

Examples

cs <- make_constants()
ep <- make_enviropar()
lp <- make_leafpar()
pars <- c(cs, lp, ep)
T_leaf <- set_units(298.15, "K")

Ar(T_leaf, pars)
