e_eq_water_mk

typhon.physics.e_eq_water_mk(T)

Calculate the equilibrium vapor pressure of water over liquid water.

$$\begin{array}{rl}\ln (e_{\mathrm{liq}})& =54.842763-\frac{6763.22}{T}-4.21\cdot \ln (T)\\ & +0.000367\cdot T+\tanh (0.0415\cdot (T-218.8))\\ & \cdot (53.878-\frac{1331.22}{T}-9.44523\cdot \ln (T)+0.014025\cdot T)\end{array}$$

Parameters:

T (float or ndarray) – Temperature [K].

Returns:

Equilibrium vapor pressure [Pa].

Return type:

float or ndarray
