Question

A wind turbine has a total input power of 2 500 kW.

The efficiency of the wind turbine is 20%.
What is the useful output power of the turbine?
​

Answer 1

Output power = 500 KW

Step-by-step explanation:

Given the following data;

Efficiency = 20%

Input power = 2500 KW

To find the output power;

`Efficiency = \frac {Out-put \; power}{In-put \; power} * 100`

Substituting into the equation, we have;

LET Output power = OP

`20 = \frac {OP}{2500} * 100`

Cross-multiplying, we have;

`20 * 2500 = OP * 100`

`50000 = OP * 100`

`OP = \frac {50000}{100}`

Output power = 500 KW
