A steam pipe is covered with 1.50 centimeter thick insulating material of thermal conductivity of 0.200 cal/cm•°C•s. Determine how much energy is lost every second when the steam is at 220°C and the surrounding air is at 20°C? The pipe has a circumference of 800 centimeter and a length of 50 meter. Ignore losses through the ends of the pipe.
