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 is 45 W/m.K and the k for the insulation is 0.182.
