Nitrogen - Thermal Conductivity vs. Temperature and Pressure

Calculate and view the thermal conductivity of nitrogen at various temperatures and pressures. Thermal conductivity describes the ability to conduct heat and is given in multiple units: mW/(m K), Btu(IT)/(h ft °F), (Btu(IT) in)/(h ft² °F), and kcal(IT)/(h m K).
