b) Superheated steam at 550 °C is transported from a boiler to the turbine of an electric power plant through a pipe. The pipe has a thermal conductivity of 0.1 W/m-K, an inner diameter of 30 cm and a wall thickness of 20 cm. The air surrounding the pipe is at 20 °C. The inner and outer convection heat transfer coefficients are 600 W/m²-K and 6 W/m²-K, respectively. Neglect radiation heat transfer. Determine the rate of heat loss per unit pipe length.
