The provided flowchart explains the process of the production of electric power in a power station using water. Here the dam was constructed across the river to store water for hydropower production. During day time: they supply the water, which is stored at a high level using a dam through a small channel. Here the channel is connected to a power station, where the power production takes place. The water with a high head comes and hits the turbine through a nozzle. Because of these forces, the turbine rotates. They connect the turbine to a generator using a shaft. It produces the electricity in a generator. The produced power is supplied to a national grid by using power lines. Here the tank is constructed to store the water, which comes out from a turbine. While at night, the water stored at low-level storage is made to push to a high-level reservoir using a water pump through the same channel. Because of this, we can use the same water for the production of electricity many times.
