If a Steam Engine Operates at Half of Its Theoretical

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

A) W 1 − e_max /2) / 2e_max
B) 2W 1 − e_max) / e_max
C) W 1 − e_max) / e_max
D) W 2 − 2e_max/2) / e_max/2)
E) 2W 1 − e_max/2) / e_max
