A schedule 40 type 304 stainless steam pipe with a 4 in. nominal diameter carries saturated steam at 150 psia in a processing plant.

Calculate the heat loss per unit length of pipe if it is bare and the surrounding air is still at 68?F. How much would this heat loss be reduced if the pipe were insulated with a 1 in. layer of 85% magnesia insulation? [Qsaved ≈ 127 W/m.
