Yes In The Groove. I started thinking about that too when Phil brought up the Bennie guys in dive gear. That water has to be no warmer than 32.001 F! And I bet that you have a bit of trouble having a divers BRASS HAT maintain a warm temperature. I guess the dive compressor warms the air a little as it is placed under pressure but the helmet is surrounded by freezing water the whole time. How about it Phil?
->greyhoundollie The air is warmed by compressing, but by the time it makes its way through a hundred feet of exposed hose and then when the pressure is released into the hat it comes out quite cool! You head is not generally touching the hat so there is little conduction there. For cold water you rug up in thermals and work hard!
Cheers Phil
