An insulated steam pipe passes through a room in which the air and walls are at 25°C. The outside diameter of the pipe is 70 mm, and its surface temperature and emissivity are 200°C and 0.8, respectively. Determine the surface emissive power and irradiation. Also, find the rate of heat loss from the surface per unit length of pipe.
