## <Fundamental of Heat Transfer Calculators

Heat Transfer According to Fourier's Law
​ Go Heat Flow Through a Body = -(Thermal Conductivity of Material*Surface Area of Heat Flow*Temperature Difference/Thickness of The Body)
Newton's Law of Cooling
​ Go Heat Flux = Heat Transfer Coefficient*(Surface Temperature-Temperature of Characteristic Fluid)
Heat Flux
​ Go Heat Flux = Thermal Conductivity of Fin*Temperature of Conductor/Length of Conductor
Heat Transfer
​ Go Heat Flow Rate = Thermal Potential Difference/Thermal Resistance
