A typical wind turbine extracts 40% of the kinetic energy of the wind that blows through the area swept by the blades. For a large turbine 110,000 kg of air moves past the blades at 13 m/s every second.

A. Sketch the turbine and the air passing ‘through’ it.

B. How much power does the turbine extract?

C. If the turbine converts 80% of the power into electric energy, how much electric power is produced?

The opposite of a wind turbine is an electric fan: The electric energy that powers the fan is converted to the kinetic energy of moving air. A fan is putting 1.0 J of kinetic energy into the air every second. Then the fan speed is increased by a factor of 2. Air moves through the fan faster, so the fan moves twice as much air at twice the speed. How much kinetic energy goes into the air every second? Note:...

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) Will the turbine’s wake have a smaller, larger, or the same cross-sectional area compared to the area the blades sweep out. Why? Calculate this area. Hint: At velocities much lower than the speed of sound, with small pressure...

Exploring Innovation in Action Power to the People – Lifeline Energy Trevor Baylis was quite a swimmer in his youth, representing Britain at the age of 15. So it wasn’t entirely surprising that he ended up working for a swimming pool firm in Surrey before setting up his own company. He continued his swimming passion – working as a part-time TV stuntman doing underwater feats – but also followed an interest in inventing things. One of the projects he began...

Muffler Magic* Muffler Magic is a fast-growing chain of 25 automobile service centers in Nevada. Originally started 20 years ago as a muffler repair shop by Ronald Brown, the chain expanded rapidly to new locations, and as it did so Muffler Magic also expanded the services it provided, from muffler replacement to oil changes, brake jobs, and engine repair. Today, one can bring an automobile to a Muffler Magic shop for basically any type of service, from tires to mufflers...
