Heat Transfer Calculator in Physics

Formulas Used in Thermal Calculations

Heat transfer analysis relies on thermodynamic principles. This tool supports conductive and specific thermal energy equations.

1. Fourier's Law of Thermal Conduction

For steady-state conduction through a uniform material, rate of heat transfer ($q$) is expressed as:

• $q$: Heat transfer rate per unit time in Watts (W) or Joules per second (J/s).
• $k$: Thermal conductivity of material expressed in $\text{W/(m}\cdot\text{K)}$.
• $A$: Surface cross-sectional area perpendicular to heat direction in $\text{m}^2$.
• $\Delta T$: Temperature difference across material layers in Kelvin (K) or Celsius (°C).
• $\Delta x$: Total material thickness or travel distance in meters ($\text{m}$).

2. Specific Heat Capacity Equation

To calculate total heat absorbed or lost by mass during temperature shifts, use:

• $Q$: Total heat energy transferred in Joules (J).
• $m$: Mass of object measured in kilograms ($\text{kg}$).
• $c$: Specific heat capacity measured in $\text{J/(kg}\cdot\text{K)}$.
• $\Delta T$: Net temperature change ($\text{T}_{\text{final}} - \text{T}_{\text{initial}}$).
