For a short time yesterday we got some rain. Part of the was fairly heavy. Talking with one of my customers that lives just down the road from me when he checked his rain gage he had two inches of rain.
When we talk of rain we always talk about how many inches we get but never in how many gallons that really is. So here we go.
A gallon of water is 231 cubic inches of water. That's our starting point.
So we're going to deal with just one inch of rain spread over an acre of land. Let's see how my math goes.
A one foot square area is 144 square inches and it will hold 144 cubic inches of rain if it rains one inch.
A acre is made up of 43,560 square feet. Now we know that every square foot with one inch of rain is 144 cubic inches of water.
Now let's multiply 144 inches by 43,560 to get the number of square inches in an acre. That comes out to 6,272,640 square inches to make up an acre of land.
At an inch of rain that is the same number of cubic inches. So if we take 6,272,640 cubic inches and devide that by 231, the number of cubic inches of water in one gallon, we find that on one acre of land or lake you end up with 27,154.285 gallons of water.
Anyone want a glass of water?
