1) The time for a hydroelectric plant reservoir to reach half of its useful height.
Knowing that this reservoir is 10km long and 278m wide, which today the inflow
into the reservoir is 330m /s and outflow is 531 m/s. And that the current useful
height is of 750m.
2) The minimum mass flow in kg/s required to maintain energy production of
152MW per turbine, knowing that the minimum height in the reservoir for the
plant's operation is 375m. One time that this system is composed of 8 turbines
what will be the volumetric flow (m³/s) that needs to be reached to the reservoir
so that the production of this amount of energy per turbine is maintained. Note:
disregard the effect of kinetic energy; specific mass of water equal to 1000 kg/m³;
g = 9.81 m
