A copper rod, an aluminum rod, and a brass, each 6.00 m length and 1.00 cm diameter, are placed end to end with the aluminum rod between the other two. The free end of the copper rod is maintained at water’s boiling point, and the free end of the brass rod is maintained at water’s freezing point. If T1 and T2 are steady-state temperature copper-aluminum junction and aluminum-brass junction respectively. Where TC is temp at freezing point of water and TH is temp at boiling point of water. Show that the steady-state temperature for (a) the aluminum-brass junction is:
In boiling water at 1 atm pressure outside a stainless-steel tube with a surface temperature of 410F, the heat-transfer coefficient h in the absence of radiation is 32 Btu/h*ft^2*F. If the emissivity of the stainless steel is 0.8, will radiation significantly augment the rate of boiling (e.g., by more than 5 percent)? Assume that the vapor film is transparent to radiation and the boiling liquid is opaque.
Consider a hot dog being cooked in boiling water in a pan. Would you model the heat transfer to the hot dog as one-, two-, or three-dimensional? Would the heat
transfer be steady or transient? Also, which coordinate system would you use to solve this problem, and where would you place the origin? Explain.

The temp of liquid nitrogen in a tank open to the atmosphere at sea level will remain constant until it is depleted. Any heat transfer to the tank will result in the evaporation of some liquid nitrogen, which has a heat of vaporization of 198 kJ/kg and a density of 810 kg/m² at 1 atm. Consider a 3-m-diameter spherical tank that is initially filled with liquid nitrogen at 1 atm and -196°C.
