The mass of water will vary. The mass of water entering the system will depend on the temperature of the water as mass is measured in terms of a standard volume. As the temperature rises and falls, the enery change of the molecules will increase or decrease the number of molecules that are needed to fill the standard volume. As water travels through the system the temperature will rise due to the frictional forces of the containment vessels and the conversion that occurs as energy is converted between potential and kinetic energies and the work being done by the exchange of energy.

That does not really answer the question: what is the mass of water used? Mass of a given volume of water does depend on its temperature hence density, but the differences with seasonal temperature range in the power-station's location are negligible.
The water will gain some heat as explained, but by then it's done its work in the turbines and is on its way back to the river below the power-station. (This was the principle of the experiments by which the pioneering scientist Henri Joule discovered the relationship between energy forms, and the fundamental Systeme Internationale unit of energy is named after him - the Joule (J). )

One cubic metre of cold, fresh water in a reservoir weighs one tonne, for all practical purposes. The actual mass per hour of water used by each turbine depends entirely on the size of the turbine and the operating conditions - full-flow or throttled back.

What two energy transformations that occur in a hydroelectric power station?
The potential energy of water stored in a reservoir is converted into kinetic energy as it flows through turbines in a hydroelectric power station. The kinetic energy of the spinning turbines is then transformed into electrical energy by the generator connected to them.
What is the ultimate source of energy in hydroelectric power station?
The ultimate source of energy in a hydroelectric power station is the gravitational potential energy of water. Water stored behind a dam has gravitational potential energy due to its elevation, which is converted to kinetic energy as it flows downhill through turbines, generating electricity in the process.
How does the hydroelectric power station work?
A hydroelectric power station works by utilizing the flow of water to spin turbines connected to generators, converting kinetic energy into electricity. Water is typically stored in a reservoir and released through pipes to drive the turbines. The amount of electricity generated depends on factors like water flow rate, turbine size, and head height.
What factor has the biggest impact on the electricity produced in a hydroelectric power station?
The biggest factor that impacts the electricity produced in a hydroelectric power station is the water flow or water volume available. The amount of water flowing through the turbines directly affects the power output generated. Other factors that can influence electricity production include the head height, turbine efficiency, and overall plant design.
How is the sun involved in hydroelectric power?
The sun is indirectly involved in hydroelectric power through the water cycle. The sun's energy causes water to evaporate from oceans and other water bodies, forming clouds that eventually lead to precipitation. This precipitation fills reservoirs behind hydroelectric dams, providing the water needed to generate hydroelectric power.
What is another name for hydroelectric power station?
water
What is hydroelectric power stations?
A power station that harnesses power from running water.
What does a hydroelectric power station look like?
Typically, hydroelectric power station appears to be a dam holding back a reservoir of water. Inside are turbines that turn the water to steam to produce electricity.
Can you put the word hydroelectric in a sentence?
In hydroelectric power station we use the potential energy of water to generate electricity.
What does a hydroelectric power station need to function?
In order for a hydroelectic power station to function, the station will need a large supply of water. The station will also require large generators with turbines in order to create power from the pressure of the water.
How was hydroelectric power made?
Hydroelectric power is made from water.
What is Hydroelectric power produced by?
Hydroelectric power is produced by running water.
What two energy transformations that occur in a hydroelectric power station?
The potential energy of water stored in a reservoir is converted into kinetic energy as it flows through turbines in a hydroelectric power station. The kinetic energy of the spinning turbines is then transformed into electrical energy by the generator connected to them.
Problem of power station in the rainforest?
THE main type of power station in the rain forest is a hydroelectric one that gets power from the energy made by water (look up hydroelectric power stations to see how they work). In order to do this the power station needs to have two or more huge reservoir's. Huge amounts of forest are flooded to make these reservoirs killing animal and plant life in the process.
What is the ultimate source of energy in hydroelectric power station?
The ultimate source of energy in a hydroelectric power station is the gravitational potential energy of water. Water stored behind a dam has gravitational potential energy due to its elevation, which is converted to kinetic energy as it flows downhill through turbines, generating electricity in the process.
What is hydroelectric energy or hydroelectric power?
hydroelectric energy is energy that comes from water
