WebIn thermodynamics and in mechanics, the heat transfer coefficient (or film coefficient) is the proportionality coefficient between the heat flux and the thermodynamic driving force for the flow of heat. It is used in calculating the heat transfer, typically by convection or phase transition between a fluid and a solid. WebThis calculator provides the natural convection coefficient. Calculation algorithms and formulas are based on Natural Convection Heat Transfer Coefficient Estimation …
= overall heat transfer coefficient (W/(m 2 ·K)) = heat transfer surface area (m 2) = logarithmic mean temperature difference (K). The overall heat transfer coefficient takes into account the individual heat transfer coefficients of each stream and the resistance of the pipe material.
