In chrras/climateeng: Tools to Calculate Climatic Comfort Related Parameters

Description

Calculates partial water vapour pressure. Eq. 36 - ASHRAE Fundamentals Handbook 2002, Psychrometrics.

Usage

alt	Vector of altitudes [m]. Defaults to 0 m (sea level).

Value

Returns a vector of partial water vapour pressure [kPa].
