Show transcribed image text (2.47) A horizontal steam pipe has an outer diameter of 8.9 cm and passes through a large room whose walls are at 293 K. The pipe 85. The air temperature in the room is 296 K. Calculate the rate of heat as a temperatureo loss per unit length from the pipe by radiation and natural convection. Ans. 281 W/ m of pipe by radiation; 206 W/m of pipe by convection.
