Why the type of energy stored in water at the reservoir is different from the energy stored in water at the penstock and turbine hydrppower?
The energy stored in water at the reservoir is gravitational potential energy due to its height above the turbine. As the water flows through the penstock and turbine, this potential energy is converted into kinetic energy and then ultimately into mechanical energy to turn the turbine and generate electricity. So, the type of energy changes as the water moves through the components of a hydropower system.

Why Water is stored in a high reservoir to run a turbine why?
Water is stored in a high reservoir to create potential energy due to its elevation. When the water is released and flows down to run a turbine, the potential energy is converted into kinetic energy, which turns the turbine to generate electricity. Storing water in a high reservoir allows for efficient energy production and control of electricity generation.
What causes the turbine of a hydro-electric dam to turn?
The turbine of a hydro-electric dam turns when water from the dam's reservoir flows through it at high pressure, causing the turbine blades to spin. This spinning motion is then transferred to a generator, where it produces electricity through electromagnetic induction.
A hydropower reservoir is an example of what kind of potential energy?
A hydropower reservoir is an example of gravitational potential energy, where the stored water has the potential to produce electricity when it flows downhill through a turbine.
What causes turbines to spin in hydroelectric power?
Turbines in hydroelectric power are spun by the force of flowing water from a dam or reservoir. The water flowing through the dam exerts pressure on the turbine blades, causing them to rotate. This mechanical energy is then converted into electricity by a generator connected to the turbine.
How can you store energy from a water turbine?
One way to store energy from a water turbine is to use a system of batteries to store the electricity generated. Another approach is to convert the energy into potential energy by pumping water uphill to a higher reservoir, which can later be released to drive the turbine and generate electricity when needed. Additionally, excess energy can be converted into other forms such as compressed air or hydrogen for storage.
What is the function of the penstock?
A penstock is a pressure conduit that delivers water from a reservoir to a turbine generator in a hydropower plant. It controls the flow of water and maintains high pressure, allowing the water to generate power as it flows through the turbine.
What is difference between penstock and pressure shaft?
A penstock is a pipe that carries water from the reservoir to the turbine in a hydroelectric power plant, while a pressure shaft is a vertical pipe that carries water under pressure from the penstock to the turbines. The penstock is typically horizontal and submerged in water, while the pressure shaft is vertical and carries water at high pressure.
How is hydroelectric form?
Well, how was hydroelectricity formed. First of all people built dams in order to make a reservoir ( man made lake). All the water from the reservoir would then go down the penstock ( a water tube). The penstock would then lead into the turbine ( fan with spinning blades ) . Water would then strike the blade and cause the blade to rotate. The rotating motion would then cause electricity. The generator would guide the turbine through the way. The electricity would then get sent through the power lines.
Why is the runaway speed of a hydraulic turbine always kept twice its normal speed?
The runaway speed of a hydraulic turbine is the speed at which the turbine coupled to the generator runs at the maximum possible speed due to loss of load and this happens until the shut off valves completely closes the discharge from the penstock. the runaway speed of the turbine is determined by the turbine designer and is influenced by the maximum discharge of water from the penstock, the combined inertia of the turbine runner and the generator and the flywheel. this factor can vary from 1.5 up to 3 times the nominal speed of the turbine and is determined by the turbine designer considering all the load parameters.
How does the water turbine do what it does?
Water traels thru a pipe called a penstock then hits a turbine and the force makes the turbine spin. The energy created travels thru copper coil and goes to the generator. the water meanwhile goes to the river
What is function of penstock?
A penstock is a conduit or pipe that delivers water from a reservoir to a turbine in a hydroelectric power plant. Its primary function is to control and regulate the flow of water, thereby maximizing the efficiency of energy generation. Penstocks are designed to withstand high pressure and are often equipped with valves to manage water flow effectively. By funneling water with precision, penstocks play a crucial role in converting hydraulic energy into electrical energy.
Why Water is stored in a high reservoir to run a turbine why?

Storing water in a high reservoir allows for efficient energy production and control of electricity generation.
What is hydro power plant reservoir?
it is energy regeneration power plant in which water is used to generate power.water is moving on turbine and then turbine moves so energy stored in the resrvoir yhat is called as hydro power plant reservoir.
How does the water get cleaned from the reservoir to your house?
the turbine that in the generator of the dam takes all the dust out of it.
What is a different between the turbine and genetrators?
A turbine drives a generator.
What converts the potential energy of a reservoir into the kinetic energy of a spinning turbine?
The potential energy of a reservoir is converted into the kinetic energy of a spinning turbine through a hydroelectric power plant. When water is released from the reservoir at a higher elevation, it flows through turbines connected to generators, causing them to spin and produce electricity. This process harnesses the gravitational potential energy of the water and converts it into mechanical energy that drives the turbines.
What is main inlet valve used in hydroelectric power plant?
Main inlet valve or shortly we say MIV is the spherical valve which installed before water enter into spiral casing of the hydro turbine.Water from the dam go to the penstock and before water enter the turbine, MIV is a component in between stop the water for small maintenance purpose in the turbine hall
