psychrometric_vapor_pressure_wet(pressure, dry_bulb_temperature, wet_bulb_temperature, psychrometer_coefficient=None)¶
Calculate the vapor pressure with wet bulb and dry bulb temperatures.
pint.Quantity– Vapor pressure
Notes\[e' = e'_w(T_w) - A p (T - T_w)\]
\(e'\) is vapor pressure
\(e'_w(T_w)\) is the saturation vapor pressure with respect to water at temperature \(T_w\)
\(p\) is the pressure of the wet bulb
\(T\) is the temperature of the dry bulb
\(T_w\) is the temperature of the wet bulb
\(A\) is the psychrometer coefficient
Psychrometer coefficient depends on the specific instrument being used and the ventilation of the instrument.
