Victoria's water problem.

How many K's are we talking? Its hard to imagine that no pumping will be required. Stringing a bluddy great big pipe across the Bass Strait will require passengers on the ferries to duck when it goes under the pipeline..... How many tankers will have to go around the strait? Plus which we all know its uphill to the equator

It's not all that far-fetched. The city of Phoenix, Arizona, gets much of its water from the Colorado River. The water is carried to the city in open aqueducts (what have the Romans ever done for us? ) spanning several hundred miles in total. Even with the high evaporation loss in the desert, it is economically worthwhile.

This idea is certainly worth a look.

Assuming that 10m of water = 1 atmosphere = 14.7psi then:
200m of head = 294psi
450m of head = 661psi

The water will definitely come out the other end, no questions. The frictional losses will slow it down, but the water will flow. I'll leave it for those with a better head for maths to work out the frictional losses.

Well the water pipeline from Prospect reservoir is about 2m in diameter. It supplies western Sydney so any pipeline would need to be as big or bigger.
