The energy driving the water cycle comes from radiant energy released by the sun that heats the water and causes it to condense.
True
False
Humans first learned to harness the potential energy in water by using waterwheels.
True
False
A component of HEPP that converts hydraulic energy to mechanical energy.
Penstock
Turbine
Generator
Turbogenerator
The following statements are true about hydropower, except for one, and that is:
The term ‘hydro’ originated from the Latin word for "water" and thus hydropower is the energy contained in water.
The power output from the scheme is proportional to the flow and to the head.
Hydropower transforms the potential energy of a mass of water flowing in a river or stream with a certain vertical fall (termed the “head”).
Hydropower is considered a renewable energy source.
After passing through the turbine, the water returns to the river through a short canal called
Taildog
Tailflow
Tailrun
Tailrace
It is a fact of nature that moving a magnet near a conductor causes an electric current.

Loboc Dam
Whenever a hydropower plant is set up in a remote area in order to meet the local demands then such a hydropower plant is known as:
Connected to the Grid
Insulated System
Connected to the System
Isolated System
When the run off from a single hydropower plant is diverted back into river or for any other purpose other than power generation, it is called:
Solo System
In a Relationship Stage
Single Stage
Cascade Stage
When two or more hydropower plants are used in parallel connection such that the runoff discharge of one hydro power plant is used as the is a intake discharge of the second hydro power plant, it is called a Cascade Stage.
True
False

Falls
The figure shown is an example of a:
Wind Plant
Wind Power Plant
Tidal Plant
Wave
When the velocity of water i.e. potential energy flowing in the stream is used for conversion into electrical power, then the system is known as In-Stream.
True
False
Sana
Alls
During off-peak hours, the reversible units are supplied with the excess electricity available in the power grid which then pumps part of the water of the tail-water pond back into the head-water pond.
Reservoir (Storage-Type) HEPP
Pumped-Storage Type
Run-off River Type
Medium Capacity
Assured flow for hydro power generation is more certain for the storage schemes than the run-of-river schemes.
True

When the water used in hydropower project is to be used for other purposes like irrigation, flood control, or fisheries then such a project is known as:
Cascade System
Multipurpose System
Multistage System
It's Complicated
___ applications use river current or tidal flows to produce energy. These applications do not need to dam or retain water to create hydraulic head, because the head is only a few meters.
