As shown in Figure Q3(a), an infinitely long cylindrical shell conductor A is surrounded by another infinitely long cylindrical shell conductor B, and they have the common center. The conductor A has the inner and outer radii of $R_1$ and $R_2$. The conductor B has the inner and outer radii of $R_3$ and $R_4$. Figure Q3(b) is the sectional view of Figure Q3(a). Two currents evenly passing through these two conductors have the magnitude of $I_1$ and $I_2$, with the opposite direction. Find the magnetic field distribution in terms of the distance $r$ from the common center, including the region labelled (1), (2), (3), (4), and (5).

3. Methane ($CH_4$) is burned with excess air in a boiler furnace. All reactants enter the furnace at 25 °C, 1 atm and 100% conversion is achieved in the furnace for methane. $CH_4$ (g) + 2$O_2$ (g) ? $CO_2$ (g) + 2$H_2O$ (g) a) If furnace is adiabatic and the percentage of excess air is 10%, what is the final temperature (K) of the stack gas? (15 points) b) If the final temperature is 1400 °C, calculate the percentage of excess air. (15 points) Use the following simplified heat capacities of the stack gas components: please pay attention to the units $CH_4$ (g): $C_p$ = 34.31 J/(mol-°C) $CO_2$(g): $C_p$ = 36.11 J/(mol-°C) $H_2O$ (g): $C_p$ = 33.46 J/(mol-°C) $O_2$: $C_p$ = 29.11 J/(mol-°C) $N_2$: $C_p$ = 29.00 J/(mol-°C) Heat of formation $CH_4$ (gas): -74.85 kJ/mol, $CO_2$ (gas): -393.5 kJ/mol $H_2O$ (gas): -241.83 kJ/mol, $H_2O$ (liquid): -285.84 kJ/mol
