The maximum height of a siphon with water is about 10m, depending on air pressure and temperature. So it will not work. Pumping is necessary to keep the pressure at the highest point above the vapour pressure of water at ambient temperature. And as pointed out, for any significant flow over the distances involved, frictional losses mean that the energy required to maintain this pressure are so great that alternatives (such as desalination) look more attractive.

John, I think it was a joke. :lol2:

I think the non-feasability arguement is a load of BS, water is already pumped to alot of places..Perth to Kalgoolie is 1 I can think of..It nly needs to feed into a couple of major river systems and it will find its way south, but I guess it will come to more of who will get payed and who will pay more than the capital cost..

Oh and its still raining...

Its not a half bad drizzle is it Ean? Stopped long enought for the BBQ yesterday.

Easo

We are just down the track so send some to us. At this point we are heading for the driest year on record with only 62mm so far this year. The only problem is getting the water past the Berrimah line.:o :) Yes I live in down town Alice Springs.

I've lived in the top end for 30 years and I cant remember a december this wet?

The problem we have is it rains for such a short period of time most of our rain falls in 3 months - Ok it's a lot, but most of it ends up in the sea (good for prawns)

if it was over 5 or 6 months it would be a paradise up here.

Keep things a little bit cooler. Just a bit.

Sad to hear that its that dry, a classic reasoning for a water grid of some sort as im sure the amount of water that runs over the wall at manton dam could be put to better use..
I think K dud is more intrested in spending it on helping the asylum seekers than the people who pay his wages..
Maybe its just me who cant understand it..Oh well it can go with all the other things I dont understand..

Yep we all live in one very big asylum that others seek residency in, at great potential personal risk.

We aren't good at solving why we're all in this big asylum, but we are experts at self-medication. :)
