Question

1-D, steady heat conduction temperature profile for a composite slab is given in the figure. What will be the relation between ${\text{T}}_4$ and other temperatures for the given profile?

• A. ${\text{T}}_4={\text{T}}_2$
• B. ${\text{T}}_4>{\text{T}}_1$
• C. ${\text{T}}_4=\frac{{\text{k}}_1{\text{T}}_1+{\text{k}}_2{\text{T}}_3}{{\text{k}}_1+{\text{k}}_2}$
• D. ${\text{T}}_4>{\text{T}}_2$

Answer 1

The correct option is A ${\text{T}}_4={\text{T}}_2$

${\text{T}}_4={\text{T}}_2$

Because, heat conduction is taking place only in one direction.
