A student investigates the efficiency of a scale model of an electricity generating wind turbine using the equipment in figure 1.
the student changed the number of sales on the turbine and measures the power output from the turbine's generator. the air blower is supplied with 533w and has efficiency of 0.62.
when using two sails, the efficiency of turbine was 13%. calculate the power generated.

Based on the efficiency of the airblower of 62%, power generated by the airblower is 330.5 W.

What is efficiency of a machine?

Efficiency of a machine is a ratio of the work output and the work input of a machine.

  • Efficiency = work output/work input × 100%

The power generated by the airblower = ?

Power input to th air blower = 533 W

Efficiency = 0.62 or 62 %

Power generated by the airblower = Efficiency × work input/100

Power generated by the airblower = 62 × 533/100 = 330.5 W

Therefore, the power generated by the airblower is 330.5 W.
