Don't mean to rain on your 50* parade or anything, but after the first big gulp, the rest of the water will be tempered downward according to the temperature of the recharge water. Unless you're using well water, directly from the well, your water will be closer to 35* - 38* I'm guessing as the number of cattle progesses through the cycle. If your using municipal water it will be on the colder end, especially if it's lake or stream water sourced, but could possibly be on the warmer end if it's well water sourced. And "end use" waterlines running below the frost line aren't always running in "warm" soil, they're just always in "above freezing" soil. A lot of waterline is running in that transition area between the frost line and the deeper soil, which is of a more constant temp year around. If the truth were known, I'd imagine some of the waterlines installed by sometimes unscrupulous contractors aren't buried quite deep enough, but have sufficient water moving in them constantly to keep them from freezing. But the water moving through them definitely doesn't get warmer as it passes through. |
