Steady heat transfer takes place through a plane wall in the outward direction at the rate of $1500\text{ W}$. The inner surface temperature of the wall is $27^\circ\text{C}$. The entropy generation is $0.25\text{ W/K}$. The outer-surface temperature of the wall is
- A. $2.7^\circ\text{C}$
- B. $5.1^\circ\text{C}$
- C. $7.2^\circ\text{C}$
- D. $12.7^\circ\text{C}$
