ANSWER THE FF and SHOW COMPLETE SOLN:

a.) An aluminum sheet of thickness 8.3 cm and area 13 m^2 is welded on top of a brass sheet of the same thickness and area. The thermal conductivities of aluminum and brass are 205 W/m·K and 109 W/m·K, respectively. The aluminum end is kept at 20 °C while the brass end is kept at 30 °C. At the moment when the interface temperature is 24 °C, what is the heat current through the brass sheet?

(answer for this is: 102 kW)

b.) A 10.0-cm long steel rod is welded end to end to a 20.0-cm long copper rod of the same cross-sectional
area. The thermal conductivities of steel and copper are 50.2 W/m·K and 385 W/m·K, respectively. The steel end
is kept at 100 °C while the copper end is kept at 0 °C. What is the steady-state temperature at the interface
connecting the two rods?
