Dairy farms commonly mount nozzles above the feed bunk that spray cows with water to combat the effects of heat stress events. These sprinklers use potable water, which is an increasingly scarce resource on farm. It's a fact; fans alone do not provide cooling; fans circulate already warm air and offer little to no relief on hot days. To achieve cooling water must be added, the question is, how much water is needed?
