(b) A steel pipe (k = 50 W m-1 K-1) has an internal diameter of 12 cm and thickness 8 mm. The tube is 10 m long and is covered with a layer of insulation (k = 0.75 W m-1 K-1) of thickness 10 cm. Knowing that the outside temperature of the insulation is 300 K and the thermal flux from the outside to the environment is 500 W m²², calculate: (i) The thermal power (i.e., rate of heat transfer) for the entire tube. [4 marks] (ii) The temperature on the outside (T_outer) and inside (T __inner) surfaces of the pipe. [10 marks]
