For laminar flow of air over a flat plate that has a uniform surface temperature, the curve that most closely describes the variation of the local heat transfer coefficient with position along the plate is

This question is incomplete, the missing diagram is uploaded along this answer below;

from the diagram, the curve that most closely describes the variation of the local heat transfer coefficient with position along the plate is Option D

Explanation:

Given the data in the question;

We write the expression for the local Nusselt number for Laminar flow over the flat plate;

Nu =

Nu =

=    

=

Next we write down the expression for the local heat flux from the plate with  uniform surface temperature;

q = T - T∞ )

q ∝

∴

q ∝  

The local heat flux decreases with the position as it is inversely proportional to the square root of the position from the leading edge and it will not be zero at the end of the plate.

Therefore, from the diagram, the curve that most closely describes the variation of the local heat transfer coefficient with position along the plate is Option D

how is this a question? in order for me to answer it i have to understand the question
