[DeTomaso] WANTED :Meriah fans and door glass

[John Bentley]

ok, now we're talking about something completely different.  Evaporation is a great way to cool stuff.  Spraying water or alcohol (or combination of) on the radiator is very effective and is used in many places.  Heck, Mikey could probably tell us about how DC-8's needed water injection for take-off!  ok, well, maybe that was before Mikey's flyin days!

I did watch him fly an ILS in the blinding snow in a C-5A to Elmendorf AK one time.  Awesome.

When my father ran the great race, it was common for guys to put bug sprayers on the outside floorboards to spray on the radiators. In the dry hot climate they would get a huge temperature drop from the evaporating air. Going through states at a 110 degrees in cars 75+ years old the only way they could keep them from overheating is by spraying water on the radiator.

That is like the swamp coolers in Phoenix. They work in phoenix but not in humid states because the temp drop is from evaporation. There is not much evaporation in Indiana but Phoenix in the summer they are very effective.

Having said that, neither is relating to the transfer of heat from a radiator (not being sprayed with water) albeit a moist or dry climate.

>> oh, ok.  It sounded like you might have known something about the process that I missed.  Every property that I know about is different between moist and dry air (of course as a pilot you know the adiabatic lapse rate is different) so I thought you could explain this.
