1.	In figure shows an aluminium rod joined to a copper rod. Each of the rods has a length of 20 cm and area of cross section 0.20cm2. The junction is maintained at a constant temperature 40∘ and the two ends are maintained at 80∘. Calculate the amount of heat taken out from the cold junction in one minute after the steady state is reached. The conductivities are KAl=200Wm−1∘C−1 and KCu=400Wm−1∘C−1 40∘C80∘C Aluminium Copper 80∘C
Answer» In figure shows an aluminium rod joined to a copper rod. Each of the rods has a length of 20 cm and area of cross section $0.20 c m^{2}$ . The junction is maintained at a constant temperature $40^{\circ}$ and the two ends are maintained at $80^{\circ}$ . Calculate the amount of heat taken out from the cold junction in one minute after the steady state is reached. The conductivities are $K_{A l} = 200 W m^{- 1 \circ} C^{- 1}$ and $K_{C u} = 400 W m^{- 1 \circ} C^{- 1}$ $40^{\circ} C 80^{\circ} C \begin{matrix} Aluminium & Copper \end{matrix} 80^{\circ} C$

Answer»

In figure shows an aluminium rod joined to a copper rod. Each of the rods has a length of 20 cm and area of cross section $0.20 c m^{2}$ . The junction is maintained at a constant temperature $40^{\circ}$ and the two ends are maintained at $80^{\circ}$ . Calculate the amount of heat taken out from the cold junction in one minute after the steady state is reached. The conductivities are $K_{A l} = 200 W m^{- 1 \circ} C^{- 1}$ and $K_{C u} = 400 W m^{- 1 \circ} C^{- 1}$
