Hi Kallog
disadvantage of creating a long stretch of river with reduced flow rate where it's being bypassed through the penstock
I suppose you are talking about the speed of the water that
exits the system after generating the power.
if so , do you think that this water that exits the system is no longer affected by gravity?
because it is gravity that gave the water its speed in the first place.
all the water is falling at 9.8 m/s/s
it just travels horizontaly because it cant travel verticaly.
so almost as soon as the water is released from the system back into the river the water will accelerate back to its original or close to its original speed , because of gravity.
they may have already designed this into the system by allowing the discharge pipe to have a angle that would re-accelerate the water before it enters the river.
if they didnt design this into the system then the designers are probably getting kick backs from some energy interest.
because you could have back pressures on the downstream side of the turbine that could reduce power production.
I bet environmentalists would hate it for killing off fish and what not!
if environmentalist hate it for killing off fish , we can just point them to the gulf oil spills and see if they still think that way.
