Question

A steel pipeline, 2-in. schedule 40 pipe (ID: 2.067 in.; thickness: 0.154 in.), containing saturated steam at 121 C. The line is covered with 30.5 mm of insulation. Assuming that the inside surface of 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 24.4 m of pipe. The average k for steel is 45 W/ (m K) and the k for the insulation is 0.182.

Step 1

The formula for heat loss through a cylindrical wall is: Q = 2πkL(T1-T2)/ln(r2/r1) where: Q = heat loss (W) k = thermal conductivity (W/mK) L = length of the pipe (m) T1 = temperature inside the pipe (°C) T2 = temperature outside the pipe (°C) r1 = inner radius Show more…
