URGENT! Please help me! About the wind turbine and the solution of the formula!?
The amount of energy harnessed by wind second can be produced by the formula: (rA x (cube v)) / 2 r = air density, A = area swept by turbine blades, wind speed v = to ascertain the average wind speed and the length of the blades of the turbine, work out the amount of energy each turbine can produce in 3 hours? In fact, the actual amount of wind energy produced is less than that calculated. WHY?
If you know the length of the blades of the turbine, l, the area is can be calculated as pi * square l (the formula for calculating the area of a circle from the radio). The power (in watts) they can be calculated using the following formula: P = R * pi * l * l * v * v * v / 2, where L is the length of the blades, pi is approx. 3.1415 and R approx. 1.2 kg per m m. A watt is a joule per second, which means that in three hours, the energy produced is: * 10 800 P (number of seconds in three hours) This is the amount of energy produced in theory. In reality, however, you will always have losses, as losses in the turbine mechanical and electrical losses in the generator. For them, the actual energy produced always be less than the theoretical value.
