Streamgaging generally involves 3 steps: 1. Measuring stream stage —obtaining a continuous record of stage—the height of the water surface at a location along a stream or river. 2. The discharge measurement —obtaining periodic measurements of discharge (the quantity of water passing a location along a stream) 3.

However, a storage unit with an E/P-ratio of e.g. 5 h would see the same price profile but would only be able to charge for 5 h and discharge for 5 h a day due to energy storage limitations. For a storage unit with a limited E/P-ratio of 5 h, the occurring price pattern is clearly different from the actually "available" price pattern which the unit

The formula for this relationship is: E = 1/2 * Q^2 / C. Where: – E is the energy stored in the capacitor (in joules) – Q is the charge stored on the capacitor (in coulombs) – C is the capacitance of the capacitor (in farads) This formula is useful when the charge on the capacitor is known, rather than the voltage.
