| July 22, 2021 | education
These tasks: t (duration of rotation of the blades of the considered wind turbine) = 2.5 min (in SI t = 150 s); N (number of revolutions) = 75 revolutions.
The period of rotation of the blades of the considered wind turbine is calculated by the formula: T = t / N.
Let’s make a calculation: T = 150/75 = 2 s.
Answer: the blades of the considered wind turbine rotate with a period of 2 s.
