Which of the following assertions concerning hydroelectric power plants is incorrect: The cost of its capital is quite expensive. The construction of a hydroelectric power plant often takes a significant amount of time.
Why deltas are not suitable for hydroelectric power plant?
It is not possible to obtain adequate water head in locations that are arid or flat. Because of the high sedimentation rate, deltas are not suited for this purpose. 8. Which of the following statements regarding hydroelectric power plants is incorrect? b) The cost of its building is quite high, and the erection process takes a very long period.
Why are hydroelectric power plants constructed in hilly areas?
The reason that hydroelectric power facilities are built in mountainous places is so that they can obtain adequate head for their operations. It is not possible to obtain adequate water head in locations that are arid or flat. Because of the high sedimentation rate, deltas are not suited for this purpose.
How can rapidly changing load demands be met in hydroelectric power plant?
D) It is impossible for a hydroelectric power plant to accommodate fluctuating load needs in a timely manner. Changing load needs may be satisfied by just managing the flow of water utilizing valves and gates to regulate the flow of water. Because of its sturdy structure, its effectiveness does not diminish with the passage of time.
How does a hydro power plant work?
- Hydroelectric power plant multiple choice questions and answers with solutions.
- In order to generate electricity, hydroelectric power plants make use of the potential energy that is contained within water.
- The water is kept at a specific height, and then it is carried all the way down to the bottom, where it is directed into the turbines.
- The turbines are synchronized with a generator, and the output of the system is where the power is produced.
What is wrong with hydroelectric power?
- Problems of a social and environmental nature can also be caused by hydropower.
- The terrain and the rivers that are built on are radically altered when a reservoir is constructed.
- The construction of dams and reservoirs can result in decreased river flows, an increase in water temperature, a decline in water quality, and the accumulation of silt.
- Fish, birds, and other forms of wildlife will suffer as a result of these actions.
Which of the following is not true for hydroelectric energy?
Which of the following benefits associated with hydroelectric power plants is not one of them? Explanation: The output of plants like this is never completely stable. This is due to the fact that they are dependent on the seasonal variations in the flow rate of the water in the river.
Which one of the following statement about hydroelectric power is correct?
The use of hydroelectric electricity does not have any adverse effects on the surrounding ecosystem.
Which of the following statement is wrong for surge tank in hydropower plant?
- Which of the following statements regarding the surge tank is incorrect?
- In order to alleviate the penstock from an excessive amount of water hammer pressure, the surge tank serves as its primary function.
- This is accomplished by redirecting the flow of water that is rejected into the tank.
- Since pressure cannot be released from a tank that is completely closed, surge tanks often have their tops left open.
What is good and bad about hydroelectricity?
Hydroelectricity is one method of producing electricity that does not contribute to the emission of greenhouse gases. However, it can also pose environmental and social hazards, including as damage to the habitat of wildlife, a decrease in the quality of the water, an obstruction in the migration of fish, and a reduction in the advantages rivers provide for recreational use.
Which characteristic is a disadvantage of hydroelectric plants?
Both the quality of the water and its flow may be affected by hydropower. Low amounts of dissolved oxygen in the water can be caused by hydropower plants. This is an issue that is hazardous to riparian (riverbank) ecosystems and can be remedied by the use of a variety of aeration methods, which oxygenate the water.
Which one of the following statement about power station is not true?
It is not correct to say that ″electricity produced in hydroelectric power stations is different from electricity produced in thermal power stations.″
Which of the following is not the part of hydroelectric power plant?
The accumulation of sediment is not a characteristic of hydroelectric power plants in any way. Dams, water reservoirs, intake and control gates, water turbines, and penstacks are typically some of the components that are utilized in important elements of a hydroelectric power plant. Other components include control gates.
Which of the following statements is not true for hydropower generated from river dams?
- The generation of hydropower by dams is not conducive to achieving sustainable growth.
- They cause damage to forests and wildlife, as well as the natural ecosystem of rivers, which they disturb.
- It uproots thousands of native people from their homes along the rivers they depend on for survival.
- They cause a significant release of greenhouse gases and wreak havoc on food systems, the quality of water, and agricultural practices.
Which of the following statement is wrong for the steam power plant?
In a steam power plant, the economizer is responsible for which of the following statements? b) It gets its heat from the flue gases that are produced by the boiler and sent up the chimney. The temperature of the feed water can be increased with the assistance of an economizer. Intake air can have its temperature increased by using a device called a preheater.
Which among the following is true for hydroelectric power plants?
- Which of the following statements is most accurate regarding hydroelectric power plants?
- Explanation: The cost of running a hydroelectric power plant is very inexpensive, despite the substantial initial investment required.
- The initial investment is substantial because of the substantial amount of land that must be utilized for the development.
- As a result of the fuel cost being lower than average, the operational costs are relatively modest.
Which of the following is not a requirement for site selection of a hydroelectric power plant *?
The presence of sedimentation is not a prerequisite for the location of hydroelectric power plants. This is due to the fact that sedimentation can decrease a reservoir’s capacity to store water and can also cause damage to the turbine blades.
What is hydro power plant Mcq?
In order to generate electricity, hydroelectric power plants make use of the potential energy that is contained within water. The water is kept at a specific height, and then it is carried all the way down to the bottom, where it is directed into the turbines. The turbines are synchronized with a generator, and the output of the system is where the power is produced.
What is hydro power plant?
- At hydroelectric power plants, water travels through a conduit known as a penstock before pushing against and turning the blades of a turbine.
- This causes the generator to spin, which results in the production of electricity.
- Run-of-the-river systems are one type of conventional hydroelectric facility.
- In these systems, the force of the river’s current applies pressure to a turbine, which in turn generates electricity.
How does a hydroelectric power plant work?
At the plant level, water travels via a pipe that is also referred to as a penstock. This water then rotates the blades of a turbine, which in turn turns a generator, which finally creates energy. This is how the vast majority of traditional hydroelectric facilities, such as run-of-the-river systems and pumped storage systems, generate electricity.
