How far can one take evaporative cooling?  With dewpoint temperatures in the

question I asked you all in the dead of winter: given a dewpoint temperature
way below freezing, what is the warmest shade temperature at which an icicle
can form. 

 

This is the kind of question that a Massachusetts resident would never think

Hi
You need a psychometric chart for this. Here's one off the internet

No scientific results here, but some anecdotal experience from about 40
years ago. I spent two summers in west Texas (near Wink, birthplace of Roy
Orbison). I was a field tech on a project studying Desert Side-blotched
Lizards. Temperatures were often over 110 F in the early afternoon, with
humidity dropping to single digits. We all lived in small sheet metal-sided
cabins with metal roofs (it was an abandoned Air National Guard base). With
no cooling, the internal temperature would have been totally unbearable,
but they had evaporative coolers. The air from them was quite chilly, at
times I would have to turn mine off or put on a sweater. Of course, at
night, the desert cooled substantially.

[FRIAM] evaporative cooling

2020-05-19 Thread thompnickson2 
A technical question for you high-desert scientists:

 

How far can one take evaporative cooling?  With dewpoint temperatures in the
teens, how far down can the output of a swamp cooler be.  This relates to a
question I asked you all in the dead of winter: given a dewpoint temperature
way below freezing, what is the warmest shade temperature at which an icicle
can form. 

 

This is the kind of question that a Massachusetts resident would never think
of, let alone ponder on.
