Question

The number of twigs on your tree: 154,000 twigs

Based on transpiration measurements that we have made in previous years; each twigtranspires about 3 grams of water per hour on a warm spring day. That is, multiply your tree’s twigs by 3. This is a rough average for all sides of the tree (the south side, exposed to the sun, and the north side, with indirect light.) Calculate the number of grams of water per hour that your tree transpires. ____________g/hr

Now convert your grams of water to kilocalories. Remember that the evaporation of a gram of water uses about 0.6 kilocalories of heat, which comes from the air. _____________ kcal/hr

Assume that a day is 10 hours long and a month is 30 days. How many kilocalories per month does your tree account for? _________ kcal/mo

How many kilowatt hours of electricity would it take to have an air conditioner use this number of kilocalories? One kilowatt hour takes about 860 kilocalories of evaporation. Transpiration in your tree accounts for ____________ kwh/month.

How much would this many kwh costs? The national average is 13¢. $__________ per month. This is how much money it would cost you to run an air conditioner to accomplish the same amount of cooling that your tree does in a month.
