Question: Consider an infinitely long pipe with diameter D = 0.2 m. The upstream half of the pipe is insulated and the downstream half is subjected to a uniform heat flux q" = 10 kW/m2. A liquid metal (a = 5 × 10-5 m2/s) with bulk velocity V = 0.01 m/s flows slowly through the pipe. Including the effect of axial conduction, determine the axial temperature distribution within the liquid metal.
