Write legibly, provide manual step by step solution, and diagram for below given problem.

Saturated steam at 500^oK flows in a 0.20 m inside diameter, 0.21 m outside diameter pipe. The pipe is covered with 0.08 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^oK. The unit convective coefficients are h₁ = 18,000 W/m²-K and h_o = 12 W/m²-K. Determine the heat loss from 4 m of pipe.

a. 778.21 watts b. 825.80 watts c. 830. 80 watts d. 835.80 watts
