Cost of electricity by source - Wikipedia

The levelized cost of energy (LCOE) is a measure of a power source that allows comparison of different methods of electricity generation on a consistent basis. The LCOE can also be regarded as the minimum constant price at which electricity must be sold in order to break even over the lifetime of the project. This can be roughly calculated as the net present value of all costs over the

Cold Water Header Tank Overflowing: How to Replace a

The reason the cold tank seems to continue to fill after you've run the hot water is because hot water flows out fast from the hot tank, while the level of water in the cold tank only drops maybe an inch or two. So the ball only drops a bit and the valve only partly opens and the water trickles in.

Ask the Physicist!

The ideal gas law is what you need, PV/(NT)=constant where P is pressure, V is volume, T is temperature, and N is some measure of the amount of gas. For your case, N and P do not change, so V/T is unchanged as you heat the air, so V 1 /T 1 =V 2 /T. 2.
