Re: [RC] metric - Joe LongOn Thu, 10 Aug 2006 12:36:19 -0600, "Brenda K." <enduranceracing@xxxxxxxxxxxx> wrote: Geeze Joe, whether metric, imperial or otherwise, an acre (There are roughly 2 1/2 of 'em in a hectare) is a two-dimensional rather than a linear measure. So, if you want to talk gallons per acre, I guess you'd have to figure out how far you would have to go driving back and forth across an acre of land until you've covered it all. With a big John Deere and a 60-ft set of harrows, you could cover that acre in a lot fewer passes than you could with a lawn-mower that has a 42-in sweep. Of course, the Deere is going to need more fuel just to start than the Yardman will use cutting the grass. Ho ho ho. You're right, an acre is two-dimensional, but if you take a big tank with a bottom exactly one acre in area, and start pouring in water, after a while the water will begin to get deeper and deeper the more gallons you put in. The depth of the water is the linear measure -- expressed as "gallons per acre." Mathematically, it is volume divided by area, which is linear. -- Joe Long jlong@xxxxxxxxxxxxx http://www.chiprider.com =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Ridecamp is a service of Endurance Net, http://www.endurance.net.
