Question

-An iron bar (L:= 0.1 m, A, = 0.02 m. K =79 W/m K) and a brass bar (L2 – 0.1 m, A2 = 0.02 m.K2 = 109 W/m K) are soldered end to end as shown infigure.The free ends of the iron bar and the brass bar aremaintained at 373 K and 273 K respectively. Obtainexpressions for and hence compute(a) the temperature of the junction of the two bars(b) the equivalent thermal conductivity of thecompound bar(c) the heat current (rate of flow of heat) through the compound bar.​
