What is the heat loss, in Btu/h-ft (W/m) from a 40 psig (2.76 barg) saturated steam line assuming an outer wall temperature of 100°F (37.8°C)? The line has an outer diameter of 8.625 in (219mm) and there are 2in. (50.8mm) of insulation with a thermal conductivity of 0.03 Btu/h-ft-°F (0.05 W/m-K). Assume the inside and outside pipe wall temperatures are the same
