Question: The Energy Equation 7 of 13 For the questions below, consider the energy storage system shown in (Figure 1). At times of low power demand, the pump is used to move water from the lower reservoir to the upper reservoir. When power demand is high, the water can be released through the turbine to generate electricity.
Reservoir
A reservoir is an artificial lake where water is stored. Most reservoirs are formed by constructing dams across rivers. A reservoir can also be formed from a natural lake whose outlet has been dammed to control the water level. The dam controls the amount of water that flows out of the reservoir. Service reservoirs are entirely artificial and
