If youâve ever run into this annoying little Illustrator problem, it can be very frustrating, but it has a simple fix. All you have to do is set your color palette to something else, like RGB or CMYK. Now youâre good to go. Personally, I have no idea why this problem has made it all the way to CS4. If I wanted to fill a shape with a gray, Iâd choose a gray.
The theory is to build a dam on a large river that has a large drop in elevation (there are not many hydroelectric plants in Kansas or Florida). The dam stores lots of water behind it in the reservoir.Near the bottom of the dam wall there is the water intake.s to how this generator works, the Corps of Engineers explains it this way : A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.
Dams block the flow of a river or stream and create a lake or reservoir behind them, which acts as a source of stored energy (a battery is another example of a reservoir of stored energy). The dam raises the surface water up to a great height, giving it potential energy, the potential to do work.Water flows from the reservoir and through a dam by way of a special intake gate called a penstock. It's kind of like one of those water tunnels you slide through at a water park in the summer. Water flow rate is in cubic meters per second (m 3 /s). 2  Acceleration due to gravity is 9.81 meters per second squared (m/s 2). 3  Height is in meters (m). 4  Coefficient of efficiency ranges from 0 to 1, with modern power plants having the highest efficiency.
