The speed of the tide or the speed of the wind past a turbine is called the box
‘flow speed’.
Figure 2 shows how the power output of a tidal turbine compares with a wind turbine
for different flow speeds.
Figure 2
0 1 . 4 As flow speed increases, power output increases.
Give two other conclusions that can be made using information from Figure 2.
