Nusselt number

Input(s)

h: Convective Heat Transfer Coefficient of the Fluid $\left(\mathrm{W} /\left(\mathrm{m}^{2} \mathrm{~K}\right)\right)$

L: Characteristic Length (m)

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

Output(s)

NuL: Nusselt Number (dimensionless)

Formula(s)

$$ \mathrm{NuL}=\mathrm{h} * \frac{\mathrm{L}}{\mathrm{k}} $$
