Found a hand-held instrument that should work. Next need to find up-to-date wet bulb charts and fluid-replacement guidelines.
I'm attaching a link to a site which seems to give the military's present suggestions for both wet-bulb activities and hydration/work levels. My question is to the hydration levels.
http://heat_index.tripod.com/
The attached fluid replacement guidelines state that a soldier should not drink more than 1.5 quarts of water per hour, and maximum daily intake should not exceed 12 quarts. I specifically recall drinking 18 quarts of water/gatorade a day while humping at White Sands Missile Range/Green mountains. Is the 1.5 quarts per hour/12 quart per day maximum the new standard? Would this amount change if the liquid consumed contained electrolytes(to keep the soldier from screwing-up his electrolye numbers)?
Next question: The chart says to add 5 degrees farenheit for wearing body armor, 10 degrees for MOPP suit. Would it be a good presumption to equate full football pads to the body armor number, or bump it closer to MOPP gear?
