Heat loss from a steam pipeline. a steel pipeline, 2-in. schedule 40 pipe, contains saturated steam at 121.1°c. the line is covered with 25.4 mm of insulation. assuming that the inside surface temperature of the metal wall is at 121.1°c and the outer sur- face of the insulation is at 26.7°c, calculate the heat loss for 30.5 m of pipe. also, calculate the kg of steam condensed per hour in the pipe due to the heat loss. the average k for steel from appendix a.3 is 45 w/m. k and the k for the insulation is 0.182. ans. 5384 w, 8.81 kg steam/h
