Thermal diffusivity

Input(s)

k: Thermal Conductivity $(\mathrm{W} /(\mathrm{m} \mathrm{K}))$

$\hat{\mathrm{C}}_{p}$: Heat Capacity at Constant Pressure $(\mathrm{J} /(\mathrm{kg} \mathrm{K}))$

$\rho$: Density $\left(\mathrm{kg} / \mathrm{m}^{3}\right)$

Output(s)

$\alpha$: Thermal Diffusivity $\left(\mathrm{m}^{2} / \mathrm{s}\right)$

Formula(s)

$$ \alpha=\frac{\mathrm{k}}{\hat{\mathrm{C}}_{\mathrm{p}} * \rho} $$
