Next, you'll utilize this boundary situation and solve for Fourier's 2nd Legislation to obtain The inner temperature distribution. Assuming no interior heat generation, the answer is ρ C p ( ∂ T ∂ t + v → ▽ T ) = k ▽ T displaystyle rho C_ p ( partial T about partial t + overrightarrow v bigtriangledown T)=kbigtriangledown T Metal Ine
