std::vector< double >	pipe_material_coefficients
	4th-order polynomial fit coefficients for pipe thermal conductivity

std::vector< double >	insulation_material_coefficients
	4th-order polynomial fit coefficients for insulation thermal conductivity

Detailed Description

All temperatures are in Kelvin and all lengths are in meters. The material coefficient vectors must each contain exactly 5 values representing polynomial fit coefficients (order 4 down to order 0) for thermal conductivity as a function of temperature.
