Description

Saturation water vapour pressure (kPa)

Usage

1
.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
