1.3-4. Heat Loss from 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 surface 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.

Transcribed Image Text:4.3-4. Heat Loss from 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 surface 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.
