Lesson: Wind Power Physics
In this lesson, we will learn how to describe the advantages and disadvantages of wind turbines, and which locations are suitable for wind farms.
A volume of air moving through a wind turbine has a mass of kg. If the air is moving at 5 m/s, what is the kinetic energy of the volume of air? Give your answer to the nearest megajoule.
The installed capacity of a wind turbine is the maximum power output that it can produce.
What is the installed capacity of a wind farm containing 180 turbines if the installed capacity of one wind turbine is 3.6 MW?
Which of the following is the main reason why a wind farm does not achieve its installed capacity most of the time?
The graph shows the power output of a particular type of wind turbine against the wind speed. The table shows data for the wind speed at three different sites as measured on five consecutive days.
Calculate the average wind speed for each site over the five days on which the wind speed was measured, and use this information to determine which site will produce the largest power output if a wind turbine is placed there.
