Which consequence occurs when a metallurgical process operates near Carnot efficiency?

A)Excessive heat sink capacity required
B)Increased material yield enhancements shown
C)Elevated process cooling requirements onset
D)Reduced energy input minimizes needed

💡 Explanation

Approaching Carnot efficiency implies minimal entropy generation; however, the isothermal heat rejection during the cold reservoir contact (or exhaust event) increases drastically because low entropy production requires massive exhaust; therefore, an extensive heat sink is required, rather than increased yields or lessened cooling needs.
