Now as I said earlier this formula was the only one I could find that estimates power from falling water and it is from an American website (http://www.wvic.com/hydro-works.htm).If you know of another formula please tell me.
Now it seems that you're suggesting that a tree is doing something impossible!According to your figs 0.11g per second * 60 * 60 * 24 = 9504g or 9.5 liters a day!9.5 liters a day doesn't come close to what a tree tries NOT to do!
As I said earlier I'll go though most of the math with regards to estimating how much water we can raise. we estimated earlier than we can increase this by a factor of a hundred, recently we've begun to think than we can increase this natural evaporation rate by closer to three hundred.
Does it take the same amount of energy to evaporate 1 kg of water when it is in a cube shape as it does when it is spread out a few molecules in depth with a huge surface area?
This is in imperial units and the the '11.8' is used to convert units of feet and seconds into kilowatts per hour.If we can have kilowatts per hour why not per minute?
