Reference no: EM131107214

An uninsulated steam pipe passes through a room in which theair and the walls are at 25°C. The outside diameter of the pipeis 70 mm, and its surface temperature and emissivity are 200°Cand 0.8 respectively. What are the surface emissive power (E),and irradiation (G)?If the coefficient associated with free convection heat transferfrom the surface to the air is h=15 W/m2.K, what is the rate ofheat loss from the surface per unit length of pipe, q'?
