No. 2 Sirip tipis sirkular dari logam dengan ketebalan b dilekatan pada pipa silindris sebagai promotor perpindahan panas. Sirip berada dalam lingkungan udara dengan suhu ambien Ta, dan dasar dari tiap sirip berkontak dengan pipa pada posisi r=R1, dimana suhu nya konstan Tw. Sirip kehilangan panas ke ambien melalui koefisien perpindahan panas h. Sirip logam mentransmisikan panas secara konduksi pada arah radial. (a) Tunjukkan bahwa neraca panas steady state pada elemen anular sirip menghasilkan persamaan, $$ \frac{1}{r} \frac{d}{dr} (r \frac{dT}{dr}) - (\frac{2h}{bk})(T-Ta) = 0 $$ (b) Definisikan suatu koordinat radial tak berdimensi sebagai x = $$ \frac{r}{\sqrt{\frac{2h}{bk}}} $$ dan nyatakan y=T-Ta, dan buktikan persamaan berikut menggambarkan kondisi fisik sistim $$ x^2 \frac{d^2y}{dx^2} + x \frac{dy}{dx} - x^2y = 0 $$ (c) Gunakan metoda Frobenius dan tunjukkan bahwa akar-akar persamaan indisial nya adalah $s_1=s_2=0$ (d) Tunjukkan bahwa penyelesaian umum persamaan diferensial pada (b) adalah, $$ y = a_0 \left[ 1 + (\frac{x}{2})^2 + (\frac{x}{2})^4 \frac{1}{2!} + ... \right] $$ $$ + b_0 \left\{ ln(x) \left[ 1 + (\frac{x}{2})^2 + (\frac{x}{2})^4 \frac{1}{(2!)^2} + ... \right] $$ $$ - \left[ (\frac{x}{2})^2 + \frac{3}{2} (\frac{x}{2})^4 \frac{1}{(2!)^2} \right] \right\} $$
