Why do you need pumps?? It all down hill isn't it???Originally Posted by PinHead
Anybody been to the Snowies and seen the pumps they use??
They can drain a lake 4 times the size of Sydney Harbour through the turbines in peak periods of demand then use pumps to pump all the water back up overnight. One Hydro station (No.4) I saw had 6 or 8 turbines. The pipe into each turbine was 18' dia if I remember right and through each gate valve in 1 second enough water went through to fill a bath for a person for 36 years. It was a while ago when I was there so hopefully my memory isn't too far out but the figures are prity close.
There's a pipe from Adelaide to Alice for water isn't there?? But I think it's only 3 or 4' dia.
But there aren't near as many people in Alice either so who knows what size pipe you'd need to supply even 10% of Brisbane or SE QLD. The friction in the pipe is the biggest worry when trying to pump lots of water through a too little pipe.
