Answer:

Output power = 500 KW

Explanation:

Given the following data;

Efficiency = 20%

Input power = 2500 KW

To find the output power;

[tex] Efficiency = \frac {Out-put \; power}{In-put \; power} * 100 [/tex]

Substituting into the equation, we have;

LET Output power = OP

[tex] 20 = \frac {OP}{2500} * 100 [/tex]

Cross-multiplying, we have;

[tex] 20 * 2500 = OP * 100 [/tex]

[tex] 50000 = OP * 100 [/tex]

[tex] OP = \frac {50000}{100} [/tex]

Output power = 500 KW
