. Saturated steam at 500 K flows in a 0.20 m inside diameter, 0.21 m outside diameter pipe. The pipe is covered with 0.075 m of insulation with a thermal conductivity of 0.10 W/m-K. The pipe's conductivity is 52 W/m-K. The ambient temperature is 300 K. The unit convective coefficients are hi = 18,000 W/m²-K and ho = 12 W/m²-K. Determine the heat loss (kJ/min) from 5 m of pipe.

1. Saturated steam at 500 K flows in a 0.20 m inside diameter, 0.21 m outside
diameter pipe. The pipe is covered with 0.075 m of insulation with a thermal
conductivity of 0.10 W/m-K. The pipe's conductivity is 52 W/m-K. The ambient
temperature is 300 K. The unit convective coefficients are hi = 18,000 W/m²-K and
ho 12 W/m²-K. Determine the heat loss (kJ/min) from 5 m of pipe.
