The power generated by
For the speeds
The table for the data is
When the wind speed doubles, the power increases 8 times.
Given:
The power P (in watts) produced by a windmill is proportional to the cube of the wind speed v (in mph).
Calculation:
From the given instruction, the equation is
Substituting
Hence, the equation becomes
For
For
And for
Thus, for the speeds
The table is shown below
From the table it can be concluded that when the wind speed doubles, the power increases 8 times.
