do anyone understand one dimensional steady state conduction?

this is the question

Consider the plane wall of Figure 3.1, separating hot and cold fluids at temperatures \(\displaystyle T_{\infty,1}\) and \(\displaystyle T_{\infty,2}\), respectively. Using surface energy balances as boundary conditions at \(\displaystyle x = 0\) and \(\displaystyle x = L\) (see Equation 2.34), obtain the temperature distribution within the wall and the heat flux in terms of \(\displaystyle T_{\infty,1}\), \(\displaystyle T_{\infty,2}\), \(\displaystyle h_1\), \(\displaystyle h_2\), \(\displaystyle k\), and \(\displaystyle L\).

i know the two of the formulas, but i can't find Equation 2.34

temperature distribution
\(\displaystyle T(x) = C_1x + C_2\)

heat flux
\(\displaystyle q^{''}_x = -k\frac{dT}{dx} = -kC_1\)

if anyone know how to solve this, i show picture

Please show us your attempts on problems when you post them.

thank you for interest. i'll try to find the equation 2.34 and upload the picture of the quesition

I am a little rusty in topics related to the Thermodynamics, but I will try to look it up for you. No promises that I will be able to solve it, but I think that it is not very difficult as it is obvious they want you to find [imath]C_1[/imath] and [imath]C_2[/imath].

I know that the probability is very high that I will not be able to understand the figure, but it will not be a bad idea to show it.

How are you working on this question when you cannot understand this one, which is at least 2 years less advanced?

my main courses need understanding algebra, physics, calculus, and other beginning course. i don't understand the main idea of algebra, physics, calculus, so i repeat this courses as advise from the teacher

look at my heat transfer course, it have formulas similar to calculus. i don't understand why, but i think there is main idea which i still don't understand. i understand little but confusing. at least now i understand some of physics graphs for the first time because The Highlander give nice explanation in other post
