dot-get_ps: Saturation water vapour pressure (kPa)

In tealeaves: Solve for Leaf Temperature Using Energy Balance

Saturation water vapour pressure (kPa)

Description

Saturation water vapour pressure (kPa)

Usage

.get_ps(Temp, P, unitless)

Arguments

Temp	Temperature in Kelvin
P	Atmospheric pressure in kPa
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

Goff-Gratch equation (see http://cires1.colorado.edu/~voemel/vp.html)

This equation assumes P = 1 atm = 101.3246 kPa, otherwise boiling temperature needs to change

Value

Value in kPa of class units

Examples

T_leaf <- set_units(298.15, K)
P <- set_units(101.3246, kPa)
tealeaves:::.get_ps(T_leaf, P, FALSE)
