3. 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 wall has a temperature of 410 K and an emissivity of 0.85. The air temperature in the room is 296 K. Calculate the rate of heat loss per unit length from the pipe by radiation and natural convection.
