The estimated surface temperature of the insulated pipe is based on steady-state radial heat transfer analysis. Exhaust gas properties are determined by temperature-dependent interpolation, and heat transfer within the pipe wall and insulation layers is modeled using cylindrical conduction theory. Internal convection is evaluated using the Dittus-Boelter correlation for turbulent flow, while external convection is based on natural air movement around a horizontal surface.

A tolerance of ± 2% is applied to account for uncertainty due to fluctuations in gas temperature, ambient conditions, and potential heat losses along the pipe length.
