SUMMARY

The efficiency of the heat engine is calculated using the formula e=W/Q_h, where W is the useful work output and Q_h is the heat input. In this case, the engine produces 2700 J of useful work from 8500 J of heat, resulting in an efficiency of 0.32 or 32%. This straightforward calculation confirms the efficiency of the engine without any complex variables involved.

A heat engine produces 8500 J of heat while performing 2700 J of useful work. What is the efficiency of this engine?

e=W/Q_h =2700 J/8500 J =0.32 or 32%


This just looked way to easy...hoping to have someone double check
