Liquids lost swimming in hot water distance swim?

Given water is 87 degrees Given air is 90 degrees Distance 2 miles Time swimming time around 50 min. How much fluid will be lost (sweat)? Anyone want to hazard a guess? I am thinking 3 pints? = 3 pound... I plan to weigh myself prior to and after the race. Results should be interesting.
  • Into Chris Greene Lake weighing 187. Out of Chris Greene Lake 46 and 1/2 minutes later weighing 182. Five pints of Virginia "sweet tea" later weighing 187. For some reason, my body has suddenly decided it wants me pleasingly plump. Oh, hell. Who am I kidding. I have joined the ranks of America's morbidly obese. National Runner-Up in the 2-mile Cable Swim, and pound for pound, probably the fastest in my age group.
  • Charlie Tupitza brought his bathroom scale for purposes of a quasi scientific experiment. I applaud his efforts! There is nowhere near enough quasi science in this world! Real science, yes. Pseudo science, yes to that too. But amateur quasi science that might be somewhat illuminating? Not nearly enough!

If by sweet tea, you mean your typical Southern brew of sugared tea, 5 pints would have left you somewhere in the neighborhood of 187.3 pounds. Water, by definition has a specific gravity of 1. Add enough sugar to make it sweet tea, and we're closer to a specific gravity of 1.06 (or possibly more). These are the kind of nerd experiments I like. They're even better when you go ahead and ferment the sugar to reduce the specific gravity back down to 1.

Ferment it too far, and my understanding is that you can get the specific gravity back down under 1.0. I did an article on motion sickness once, and I asked one of the experts at the Ashton Graybiel Spatial Orientation Laboratory at Brandeis University why the room seems to spin when you have hog wimperingly intense case of inebriation. He said that alcohol has slightly less density than water, and if you drink enough, your blood actually becomes a tiny bit lighter than normal, which has the effect of floating these little hair-like danglers within your vestibular system, triggering a sense of motion when you are, in fact, motionless on the bathroom tiles, awaiting your inevitable, revolting penance.
  • Jim you are not a bit obese!! How did you ever find a scale at the finish of an ow swim?

  • How can you possibly measure amount of sweat produced during swimming? Per Wikipedia, which knows everything and then some, most fluid losses in humans occur in form of urine. Some is lost through sweat, some is lost through respiration (in form of water vapor), and a couple of other excretory forms also contribute minor amounts to fluid outgo. :) Wii breaks ... Call home, ET!
  • Lost liquids not sweet... I am working on an online form for people to fill out after swims. I hope others will take a scale to open water races. Will post it's location here soon.
