(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If a steam engine operates at half of its theoretical maximum efficiency, and does work at a rate of W J/s, calculate how much heat is discharged per second.

3. The attempt at a solution

e_{max}= W/Q_{H}(Carnot)

e_{max}= W/2Q_{H}

--> Q_{H}= W/e_{max}

Wrong answer. What is my mistake?
