Tides Flashcards
Designed for hydroelectric applications in free-flowing water.
Helical Turbine
It is distinct from tidal power, which captures the energy of the current caused by the gravitational pull of the sun and Moon.
Wave Energy
Turbines rotate in the same direction regardless of the direction of flow. True or False?
True
A zone with a soft-bottomed has silt or sand. True or False?
True
This kind of tide happens when it’s directly facing the moon, and bulges towards the moon.
High Tide
It often has barnacles and seaweeds.
Hard-bottomed
It’s a shallow steep funnel shapes the river and the tides since they’re enhanced as a single wall of water.
Tidal Bore
It needs this to produce Tidal Energy.
Tidal Energy Generators
It is the highest and lowest levels of tides.
High and Low Tides
It uses the temperature difference between cooler deep and warmer shallow or surface seawater.
Ocean Thermal Energy
These turbines are mainly drag-based devices.
Vertical-Axis Tidal Turbines
What is the Tidal Period of Diurnal Tides?
24 hours and 50 minutes
These objects force the currents through a blaze.
Tidal Fences
This kind of tide occurs when the Sun, earth, and moon are aligned.
Spring Tide
It is a type of tide where high tides reach different levels and the low water drops to different levels.
Mixed Tides
Mechanical Energy of tidal currents turns turbines connected to a generator
Tidal Turbines
These are areas that are completely underwater at high tide but remain as pockets of seawater when the tide ebbs.
Tide pools
The height of the average solar tide is about ____% of the average lunar tide.
50%
It exists in a location when the seawater retreats, and reaches its lowest point for a location.
Low Tide
What are the 2 sources of Energy?
Renewable and Non-Renewable
These are very familiar with wind turbines except their below the water surface.
Tidal Stream Generator (TSG)
It is related to the Earth’s rotation and the revolution of the moon around the Earth.
Tidal Period
It is the vectorial difference between the gravitational force of the Earth and that of the moon.
Tidal Force
What are the solutions to the negative impacts?
They solved it by: Barrages that can work farther from land, and smaller Underwater Turbines that are quieter and cost-effecient.
