Renewable Fluid Power

Which of the following is NOT under the Renewable FLUID power?

• Wind Energy

• Ocean Energy

• Tidal Energy

• Solar Energy

Which of the following produce high energy efficiency?

• Conventional Energy

• Renewable Energy

Does renewable energy cost high maintenance and production?

• Yes

• No

What are the two types of wind turbine?

• Horizontal and Vertical axis wind turbine

• Small scale and large scale

• Onshore and offshore

• Fixed blade and variable blade

What is the Betz's coefficient value?

• 16/27

• 27/16

• 100%

• 50%

Which of the following characterizes a Horizontal Axis Wind Turbine (HAWT)?

• • The main shaft and blades rotate vertically.

• • The generator is located at the base of the tower.

• • The blades resemble a large propeller and spin on a horizontal axis.

• • It is less efficient at capturing wind energy compared to vertical axis wind turbines.

Vertical axis wind turbines (VAWTs) offer some advantages over horizontal axis turbines. Which of the following is NOT an advantage of VAWTs?

• They can capture wind from any direction, eliminating the need for wind direction tracking mechanisms.

• hey are generally quieter than HAWTs due to their different blade design.

• hey are more visually appealing and can be suitable for urban environments.

• hey typically have a higher efficiency in converting wind energy into electricity compared to HAWTs

Wind turbines convert the kinetic energy of wind into another form of energy. What is the most usable form of energy produced by a wind turbine?

• Thermal energy

• Mechanical energy (Wind turbine uses this internally, but not the final output)

• Chemical energy

• Electrical energy
