A 0.5-m-diameter pipe (ɛ = 0.9) carrying steam has a surface temperature of 500 K (see Fig. 1.25). The pipe is located in a room at 300 K, and the convection heat trans- fer coefficient between the pipe surface and the air in the room is 20 W/m2 K. Calculate the combined heat transfer coefficient and the rate of heat loss per meter of pipe length. %3D

A 0.5-m-diameter pipe (ɛ = 0.9) carrying steam has a surface temperature of 500 K (see Fig. 1.25). The pipe is located in a room at 300 K, and the convection heat trans- fer coefficient between the pipe surface and the air in the room is 20 W/m2 K. Calculate the combined heat transfer coefficient and the rate of heat loss per meter of pipe length. Room temperature = 300 K Pipe surface temperature = 500 K Pipe Steam ɛ=0.9 FIGURE 1.25 Schematic diagram of steam pipe for Example 1.10.
