Superheated steam at 350 °C flows through a pipe whose thermal conductivity is kp = 16 W/m.K. The inner diameter and thickness of the pipe are 26 cm and 1 cm, respectively. The surrounding temperature is 28 °C. The convective heat transfer coefficient at the steam side and the outside of the pipe is 90 W/m².K and 15 W/m².K, respectively. Derive an expression for the temperature profile across the pipe thickness as a function of the radial position r. To = 28 °C, ho = 15 W/m².K = G Ts = 350 °C h; = 90 W/m²K r2 Cross-sectional view of the pipe
