What is the minimum tidal energy required for a practical tidal plant?

That depends on the kind of plant. There are two major types:1. Tidal turbines

2. tidal barrages


1. Tidal turbines are like wind-turbines but underwater. They need a current speed of at least 1m/s to start producing energy but current models are not economically viable for anything below 2m/s


2. Tidal barrages are like dams across a bay or an estuary. Theyutilizethe difference in water level between high and low tide. They open their gates as the tide comes in to allow the water to collect behind the dam. at the highest point of the tide the gates close until low tide is reached. the water is then release via turbines until the water level behind the dam is equal to the sea level. When the tide comes in again the cycle repeats. These kind of tidal plants need a difference between high and low tide of at least 5-7 meters although the bigger the difference the better.

What group of people might be interested in knowing tidal?

Mariners, surfers, fishermen, coastal residents, and environmentalists may all be interested in knowing tidal information to plan activities, monitor sea conditions, or assess the impact of tides on coastal ecosystems.

Why did the Sudanic Kingdom rise and fall?

The Sudanic Kingdoms in West Africa rose due to increased trade and agricultural productivity, leading to wealth and power. They fell due to internal conflicts, invasions by foreign empires, and the disruption caused by the transatlantic slave trade.

What are the complications of tidal volume?

Complications of tidal volume include barotrauma (lung damage from high pressures), volutrauma (lung damage from excessive stretch), and ventilator-associated lung injury. Inadequate tidal volume can lead to hypoventilation and hypercapnia, while excessive tidal volume can cause ventilator-induced lung injury. Close monitoring and adjustment of tidal volume is important to avoid these complications.

How many megawatts do tidal turbines produce in day?

A typical nuclear power plant produces 500 to 5000 megawatts of power. If we take 2000 as average, an average plant produces 2000 megawatt hours in an hour, or 48,000 megawatt hours in a day.

But please note: Technically, this does not answer the question asked, because the question asked for megawatts, not megawatt hours. The question as asked is like asking how many horsepower a car can produce in a day.

The measure of electrical output over a period of time is a watt hour, or, in this case, the megawatt hour. So the question answered was, "How many megawatt hours does a nuclear power plant make in a day?"

What is tidal dynamics?

Tidal dynamics refer to the gravitational forces between celestial bodies, such as the Earth, Moon, and Sun, that cause the oceans to bulge and recede. These forces create the daily rise and fall of sea levels, known as tides. Tidal dynamics also impact ocean currents and coastal ecosystems.

What does MMLW mean in reference to a tidal datum?

MMLW stands for Mean Lower Low Water, which is the average height of the lower of the two low tides each day over a specific period. It is used as a reference point for measuring water levels and depths in nautical charts and tidal predictions.

What environmental impact does tidal energy have?

Tidal energy has a relatively low environmental impact compared to other sources of energy. It does not produce greenhouse gas emissions or air pollutants during operation. However, tidal energy devices can disrupt marine ecosystems, affect sediment transport, and potentially harm marine life if not properly planned and managed.

How high can the moon pull water?

The moon's gravitational pull causes tides in Earth's oceans, but the height of the tide depends on factors such as the location of the particular body of water, the shape of the coastline, and the depth of the water. Generally, tides can range from a few centimeters to several meters in height.

What is percentage of tidal power using in India?

As of now, tidal power does not play a significant role in India's energy mix. India's focus has primarily been on solar and wind energy for renewable energy sources. Tidal energy potential in India is being explored, but currently, its contribution to the country's energy generation is minimal.

Will tidal power create jobs?

Yes, tidal power projects have the potential to create jobs, particularly in the areas of engineering, construction, maintenance, and operation. These jobs can help support local economies and foster growth in the renewable energy sector.

Do any countries use tidal power if so what for?

  • The first tidal power station in the world was built in France, at La Rance, in 1966. It has a capacity of 240 MW (MegaWatts).
  • The largest in the world is the 254 MW Sihwa Lake in South Korea (2011)
  • The first in North America is in the Bay of Fundy, Canada (1984, 20 MW)
  • Russia has a small tidal power station on the Barents Sea (2006, 1.6 MW)
  • South Korea has stations to open in 2013 (90MW), 2017 (1320 MW), and three more all more than 100 MW each.
  • Scotland is opening one in Islay in 2013 (10 MW)
  • India begins construction in 2012 on a 50 MW tidal farm in the Gulf of Kutch.

What is tidal volume breathing?

Tidal volume breathing refers to the amount of air that enters and leaves the lungs during a single breath while at rest. It is typically around 500 mL for an average adult. Tidal volume is important for delivering oxygen to the body's tissues and removing carbon dioxide.

Is tidal energy drawback or disadvantage?

One drawback of tidal energy is its limited availability in certain locations with strong tidal currents. Additionally, the high capital costs associated with building and maintaining tidal energy facilities can be a disadvantage. Finally, potential environmental impacts on marine ecosystems and wildlife are also a concern for tidal energy development.

What kind of energy does the Gordon dam do for the environment?

The Gordon Dam generates renewable energy in the form of hydropower. This type of energy is considered to be more environmentally friendly compared to fossil fuels, as it does not produce greenhouse gas emissions during operation. However, building dams can have environmental impacts on river ecosystems and local communities.

What are some complications of hemodialysis?

The most frequent complications in hemodialysis relate to the vascular access site where needles are inserted. This can include infection around the access area or the formation of clots in the fistula.

What is an average tidal model?

An average tidal model is a representation of tidal patterns over a specific time period, often based on the analysis of historical tidal data. These models help predict the height and timing of tides at specific locations, aiding in navigation, coastal engineering, and marine research. They provide a baseline understanding of tidal behavior for a given area.

What are the advantages of the Severn Barrage?

The Severn Barrage could provide a substantial source of renewable energy through tidal power generation. It has the potential to produce a consistent and predictable energy output due to the reliable nature of tides. Additionally, it could help reduce greenhouse gas emissions and contribute to the UK's energy security.

What measures has the flour and grain mill products industry taken to create a safe work environment?

modern mills reduced dust generation by minimizing grain handling, reducing the velocity of grain movement, and installing enclosed conveyor systems. Protection from excessive noise was achieved by isolating work stations

What is it called when theriver becomes tidal?

When a river meets the sea and becomes influenced by tides, it is known as an estuary. Estuaries are transitional zones where freshwater from rivers mixes with saltwater from the sea, resulting in unique ecosystems that support diverse plants and animals.

What pressures are facing tidal pools?

Tidal pools face pressures such as fluctuations in temperature, salinity, and oxygen levels as a result of changing tides. Human impacts such as pollution, trampling, and collecting of organisms can also affect the health of tidal pools. Additionally, climate change and ocean acidification can pose further challenges to the fragile ecosystems within tidal pools.

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.

How much energy does Rance Estuary generate in a day?

The Rance Tidal Power Station in France generates around 600 GWh of electricity per year, which averages out to about 1.6 GWh per day.

What are the largest tidal movements called?

The largest tidal movements are called spring tides. Spring tides occur when the sun, moon, and Earth are aligned, resulting in higher high tides and lower low tides.

How does a tidal work?

When the tide is high. It intakes water. When the tide is low. It releases the water, spinning turbines, therefore creating power.
