1. The capacity factor of a certain 1.3 MW wind turbine over a year is 32%....
There is a wind turbine close to the shoreline. The turbine capacity is 3 MW, the rotor diameter is 90 meters, and tower height is 110 meter. The Cp is 43.7%. The yearly average wind speed at 10 m is 5.5 m/s. There is a potential to move the machine to a 120 meter tower. How much power is in wind at 110 & 120m height at the site? (Use the power law for wind speed calculation)
this is the full question tho 3. (20%) A certain wind turbine is rated at 5 MW and has an installed cost of $6,000,000. The capacity factor is 0.38. The turbine is paid for with a down payment of 1/10 of the installed cost and a loan. The loan interest rate, b, is 8% and the period of the loan, N, is 15 years. The economic lifetime of the turbine, L, is to be 20 years, the inflation rate is...
1. Consider a wind turbine of diameter 52 m, rated capacity 850 kW, installed at a site where the average wind power density = 700 W/ m2. The total energy output over a year = 3240 MWh. What is the capacity factor?
1. Consider a wind turbine of diameter 52 m, rated capacity 850 kW, installed at a site where the average wind power density = 700 W/m2. The total energy output over a year = 3240 MWh. What is the specific rated capacity of the wind turbine (in the units commonly specified).
. A typical commercial wind turbine costs approximately $2 million per MW of installed power and requires 5.76 TJ per million dollars of energy to manufacture the wind turbine. (a) Calculate the amount of energy that is consumed (i.e. energy invested) in the manufacture ofa 1.5 MW wind turbine, assuming that turbine manufacture requires 5.76 TJ per million dollars spent. (TJ Tera-joules 1012 joules) (b) If the wind turbine has blades that are 40 meters (radius) long and the average...

1 1. Consider a wind turbine of diameter 52 m, rated capacity 850 kW, installed at a site where the average wind power density = 700 W/m2. The total energy output over a year = 3240 MWh. What is the proportion of wind energy captured? a
1. Consider a wind turbine of diameter 52 m, rated capacity 850 kW, installed at a site where the average wind power density = 700 W/m2. The total energy output over a year = 3240 MWh. What is the average power output ?
The average modern commercial wind turbine produces 1.5 to 3 MW of power (MW = megawatt, or 1,000,000 watts). So each turbine produces enough to power to light about 30,000 60-watt bulbs, or run about 1,000 hair dryers. The typical household uses about 1200 continous watts (1.2 kilowatt) on average. Let's compare wind to some other renewable electricity sources: Nuclear: 100 US nuclear plants each produce between 500 MW and 4,000 MW - total US nuclear output is about 100,000...
An industrial wind turbine has blades that are 35 m long. On a 20?C day, wind at atmospheric pressure blows with a velocity of 12 m/s , and wind in the turbine wake only has a velocity of 11 m/s .(a) If we assume that all of the kinetic energy lost by the wind is converted to electrical energy by the turbine, then what is the power generated by this turbine? (density is 1.205 kg/m^3)(b) This turbine is rated as...
