Components of Hydroelectric Power Plant

A hydro electric power plant derives the energy from the force of fast moving water to harness energy. The demand for energy needs has impacted the environment resulting in global warming. Extensive use of non-renewable energy sources like petrol and diesel is the primary reason for environmental pollution. A major shift from non-renewable energy sources to renewable energy sources is the only solution to encounter the rising issue of environmental damage.

Question

A hydroelectric power generating system
is shown in the figure. Water flows from
an upper reservoir to a lower one passing
through a turbine at the rate of 286 liters
per second. The total length of pipe
connecting the two reservoirs is 186 m.
