Well, it does (or did) but not as freeware. Many moons ago (circa 1987) I was involved in marketing a software product called PDGS. This program was originally developed by Ford and primarily it was used to design and model shapes with double-curved surfaces. But it would also calculate the volume of a very complex shaped gas tank, for example. One time at a trade show, we demoed this feature to a manufacturer of perfume bottles. We designed an elaborate bottle, clicked the button and we had the volume. It blew their socks off -- they told us it took them two weeks to do these volume calculations manually with the precision required. I believe they subsequently spent some big bucks on a license for the software. -- |~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| | Malcolm Hoar "The more I practice, the luckier I get". | | malch(a)malch.com Gary Player. | | http://www.malch.com/ Shpx gur PQN. | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

That's a good start for us to check the rule of thumb then for our own pool. We also need to know: + How much water is in a typical 12-foot long 4-foot wide solar panel? + How many "loops" are there from a pump to the edge of the pool? + How much additional plumbing is attributed to the length of the pool? My dozen solar panels are at least 100 feet away from the pool equipment. The pool is 50 feet long with the 3 pool pumps 25 feet from one end. There are three 1.5 HP pumps moving water through the pool equipment. The pool has about 15 pop-up self cleaners controlled by one pump, the two sets of jets in the spa are controlled by another pump, and the filtration system is controlled by yet another pump. The filter itself is a roundish black cartridge about as big as an office refrigerator. I will do some calculations and report back to see if they make sense but it would be helpful to know what the "rule of thumb" is for plumbing: Q: How much water is in a typical 12-foot by 4-foot solar panel? Q: How many loops does a cleaner, filter, and double-jet spa pipes make? Q: How much additional plumbing is "below" the pool length itself?

At first I thought he was joking so I ignored the "get the manual" advice. But now, with a second person saying this, I must ask how does one "get the manual" for a pool? The pool was probably built about ten years ago by the owners at that time. I've long ago downloaded the manuals for each piece of equipment, each of which has a brand and a model stamped on it. But how do you download a manual for the pool itself? The pool doesn't have a "brand" or a "model" - or does it? Where do you look for the brand or model or serial number on a pool?

That's just stupid. You're wasting a *lot* of energy pumping the water that far, not to mention the stress on the pumps and lower output. >The pool is 50 feet long with the 3 pool pumps 25 feet from one end. >There are three 1.5 HP pumps moving water through the pool equipment. ....and you're claiming that this is a typical pool? Get real! <sniped more nonsense>

She pops in every six months or so. She's pretty darn good at starting (or in this case attempting to hijack) threads of several hundred posts. She does this by focusing OCD style on minutia, responding to every reply with disingenuous but fairly convincing politeness and gratitude, and asking many dozen follow-up questions. She starts off posing as smart but ignorant. In the end she writes a masterpiece dissertation, illustrated by boatloads of photographs, that makes it clear that she knew 100 times more about the topic than she pretended to in the beginning. She documents everything with the false pretense of it "being for the next guy." Her saccharin sweetness is nauseating, but it ensnares many. Watch and see. |
