1. The problem statement, all variables and given/known data Q=-1*K(T)*(H*W)*(dT/dx)+((I^2)(p)(dx)/(H*W)) K(T)=(197.29-.06333333(T+273)) H=0.01905 W=0.06604 I=700 p=10*10^-6 Q=some constant Please separate and differentiate to solve for Q using variables of T and x. Boundaries: T: Upper=T1 (constant) Lower=T0 (constant) x: Upper=L (constant) Lower=0 (obv. constant) 2. Relevant equations a=dT/dx ----> a*dx=dT ----> integrate ax|=T| 3. The attempt at a solution I plugged in all the values and tried to make common denominator to move dx to the Q side. But I could never get around getting rid of the dx in the numerator on the right side of the plus symbol in the original equation. Also, i wasnt sure whether to double integrate with boundaries for both integrals (was sort of weird)... Please help. Been working on this for a long time and cant figure out a way to manipulate it. Main issue is the two dx's and only one dT, so straight up integration wont work bc you would be integrating a dx when there is no dT left.
