An overhead 30-m-long, uninsulated industrial steam pipe of 120-mm diameter is routed through a buidling whose walls and air are at 30 degree Celsuis. Pressurized steam maintains a pipe surface temperature of 150 degree Celsuis, and the coeffficient associated with natural convection is h=10 W/m^2*K. The surface emissivity is E=0.8
