A wind turbine requires a specific minimum wind speed, known as the “cut-in speed,” to begin rotating and generating electricity. This speed is between 3 and 4 meters per second (approximately 6 to 9 miles per hour) for most commercial turbines. Participants explore various methods to calculate the necessary torque and RPM, as well as practical. . How much time it takes it to leave the pipe through its outlet? The length of the pipe is (L), and the air inside travels with speed (V), so thetime the "portion" in question needs to get completely out through the outlet is: [ dfrac {L} {V}=dfrac {V times Delta t} {V}=Delta t] So. . Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind is a form of solar energy caused by a. . Instead, the power output from a wind turbine is proportional to the cube of the wind speed.
