Load the file winddata.txt into a spreadsheet or workbook. The first column is a time stamp (spaced by
1s) and the second column is the measured cup rotational frequency. Apply the calibration values
obtained from the previous section to obtain a third column of wind speeds. Plot this. It should look
something like this:
What is the mean wind speed 𝑉̅ ?
What is the standard deviation 𝜎𝑣 ?
What is the turbulence intensity 𝑡𝑖 ?
(𝑡𝑖 = 100 𝜎𝑣𝑉̅[%])
