A) Added insulation increases heat loss.
B) Added insulation decreases heat loss.
C) Convection heat loss is less than conduction heat loss.
D) Heat flux decreases.
Correct Answer: C
Solution :
\[Q=\frac{2\pi L({{t}_{1}}-{{t}_{0}})}{\left[ \frac{In\,\left( \frac{{{r}_{2}}}{{{r}_{1}}} \right)}{k}+\frac{1}{{{h}_{0}}{{r}_{2}}} \right]}\] Conductive thermal resistance increases with increasing \[{{r}_{2}}\] and convective thermal resistance decreases with increasing\[{{r}_{2}}\]. \[Thus\,\,{{Q}_{convective}}<{{Q}_{conductive}}\]You need to login to perform this action.
