The rate of heat transfer from a vertical plate by natural convection depends upon the temperature differences (ΔT) between wall and outside bulk. The proportionality is given as

A $${\left( {\Delta {\text{T}}} \right)^{\frac{1}{4}}}$$
B $${\left( {\Delta {\text{T}}} \right)^{\frac{1}{2}}}$$
C $${\left( {\Delta {\text{T}}} \right)^{\frac{5}{4}}}$$
D $${\left( {\Delta {\text{T}}} \right)^{\frac{3}{4}}}$$

Correct Answer: $${\left( {\Delta {\text{T}}} \right)^{\frac{3}{4}}}$$
