RE: psychrometric properties
I've worked in water damage mitigation for over a decade and have used all kinds of psychrometric calculators over the years. I believe specialized nomographs and slide rules were also made but I haven't laid hands or eyes on these myself.

This link explains the use of a pyschrometric chart, which I was taught how to use, but I've only ever used electronic calculators for the task.

The one I used most often was sold by the Dri-Eaz company and they called it the "Digital Pyschrometric Calculator." It was made in Taiwan. Notably, it takes about one full second to run grain/specific humidity calculations. I don't remember the exact price but they were surprisingly expensive, over $40 apiece.

Below are some pictures:

There are a couple of free apps floating around which also perform pyschrometric calculations.
