A large steam pipe is covered with 1.5-cm-thick insulating material of thermal conductivity 0.27 J/(s m °C). How much energy is lost every second when the steam is at 205 °C and the outside of the pipe has a temperature of 20°C? The pipe has a circumference of 7.5 m and a length of 80 m. Neglect losses through the ends of the pipe. What is the units as well?
