Variables Used
Thermal Resistance - (Measured in Kelvin per Watt) - Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Thermal Conductivity 1 - (Measured in Watt per Meter per K) - Thermal Conductivity 1 is the thermal conductivity of the first body.
Point 1 Cross-Sectional Area - (Measured in Square Meter) - Point 1 Cross-Sectional Area at is defined as the area of the section at point 1.
Thermal Conductivity 2 - (Measured in Watt per Meter per K) - Thermal Conductivity 2 is the thermal conductivity of the second body.
Point 2 Cross-Sectional Area - (Measured in Square Meter) - Point 2 Cross-Sectional Area is defined as the area of the section at point 2.

## <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
