I know the MTE is 1-Tc/Th = 1-500/1000 = .50 = 50%

I'm not sure if I calculate the actual the same way with the Joules, or if I use n=W/Q?

If so, that would be 600J/1000K = 60% which would be higher than the MTE. Doesn't seem right...

Would the correct equation for the actual work be 1-600J/1000J = 1-.6 = .4 = 40% ?
