Temperature distribution along the radius of a long cylindrical shell was found to be -2596.8 W/m2; -1558.1 W/m2; T(r) = 365 +21.64 ln(r) all quantities in SI units. inward Since the temperature is only dependent on radius (r), the heat transfer in this case is radially one- dimensional. The thermal conductivity of cylindrical shell is 36 W/m-K. The shell has inner diameter of 0.5 m and outer diameter of 1 m. Find out the heat flux at r = 0.3 m and at the outer surface of the tube. Justify if the heat transfer is radially outward or radially inward.

A 2m^2 wall of 1010steel is 8 mm thick. If the outside of the wall is100 °C, andyou measure aheat flux of 80 kW/m2coming off the wall, what is the temperature of the insideof thewall?
