A steam pipe is covered with 1.25 cm thick insulating material of thermal conductivity 0.200 W / m. ° C. How much energy is lost every second when the steam is at 200 ° C and the surrounding air is at 20 ° C? The pipe has a circumference of 950 cm and a length of 68 m. Neglect losses through the ends of the pipe.
