How to Calculate the Efficiency of a Wind Turbine?

What calculation gives the percentage efficiency of a wind turbine?

A- 54000 / 180000 × 100%

B- 180000 / 54000 × 100%

C- 54000 × 100 / 180000 %

D- 180000 × 100 / 54000%

Answer:

The correct calculation to find the percentage efficiency of a wind turbine is option A- 54000 / 180000 × 100%.

When determining the efficiency of a device or system, such as a wind turbine, it is essential to calculate the ratio of useful output power to the input power and express it as a percentage.

In this scenario, a wind turbine generates 54 kW of useful power from an input of 180 kW of wind power. To calculate the percentage efficiency, the following formula is used:

Efficiency (%) = (Useful Power / Input Power) × 100%

By substituting the given values into the formula:

Efficiency (%) = (54 kW / 180 kW) × 100%

Calculating this equation results in:

Efficiency (%) = 0.3 × 100% = 30%

Hence, the correct calculation for the percentage efficiency of the wind turbine is 54000 / 180000 × 100%.
