A $20$ kW wind turbine with a cut$-$in wind speed of $5\frac{m}{s},$ a rated wind speed of $8\frac{m}{s},$ and a

cut$-$out wind speed of $14\frac{m}{s}$ was operating at a particular site of grasslands with a friction

factor of $0\mathrm{.}15.$ The wind turbine was installed at a hub height of $50$ m $.$ Using the data reported

in the following table, calculate the total power generation from the wind turbine for a

particular month. Assuming the grid electricity purchase price is $0\mathrm{.}08\frac{\text{\$}}{k}Wh.$ Determine the

financial benefits achieved by the utilization of the wind turbine for this month.
