Formula 5.53

Estimation of the viscosity of a pure liquid

Input(s)

$\mathrm{N}$: Avogadro Number $(\mathrm{g} / \mathrm{mol})$

$\mathrm{h}$: Planck Constant $\left(\mathrm{g} \mathrm{cm}^{2} / \mathrm{s}\right)$

$\mathrm{V}$: Volume of a Mole of Liquid $\left(\mathrm{cm}^{3} / \mathrm{g} \mathrm{mol}\right)$

$\boldsymbol{T}_{\boldsymbol{b}}$: Boiling Point (Centigrade)

$\mathrm{T}$: Ambient Temperature (Celsius)

Output(s)

$\mu$: Viscosity of a Pure Liquid $(\mathrm{g} /(\mathrm{cm} \mathrm{s}))$

Formula(s)

$$ \mu=\frac{\mathrm{N} * \mathrm{~h}}{\mathrm{~V}} * \exp \left(3.8 * \frac{\mathrm{T}_{\mathrm{b}}}{\mathrm{T}}\right) $$
