ANSWER:

Step 1 of 4

Two sites with specified wind data are being considered for wind power generation. The site better suited for wind power generation is to be determined.

Assumptions are

1. The wind is blowing steadily at specified velocity during specified times.

2. The wind power generation is negligible during other times.

We take the density of air to be  .
