The steel pipe (100 mm outer diameter) is covered with two layers of insulation. The 40 mm thick inner layer has a thermal conductivity of 0.07 W / (mK). Outer layer, 20 mm thick has a thermal conductivity of 0.15 W / (m K). The pipe is used to drain 500 kPa pressurized steam. The temperature on the outer insulation surface is 24 ° C. If the pipe is 8 m long, determine the following: (assuming that the conduction heat...
