A 1.2 MW wind turbine has a rotor diameter of 64 m. the turbine operates in an area with an average wind velocity of 7.5 m/s and the air density of 1.18 kg/m^3. the turbine power coefficient including the unit efficiency is 42.8 percent. (a) Determine the power output and the annual energy produce (b) the total installed cost is $1.2 million, and its annual cost is based on the equivalent of a 20-year, 5percent loan to cover the capital cost. the annual Debit payment (DP) is determined from DP=CRF x Total installed cost. The CRF is Capital Recovery Factor evaluated from CRF = (i(i+1)^n/(1+i)^n-1, where i is the interest rate in decimal form, and n is number of years. if the annual operation and maintenance cost 1 percent of the capital cost, determine the cost of electricity in cent/kWh.
