Under these conditions, Equation 1.47 becomes identical to the adiabatic saturation curve Equation 1.41 and thus the adiabatic saturation temperature is the same as the wet bulb temperature for the air–water system. For systems other than air–water, they are not the same, as can be seen from the psychrometric charts given by Perry [7].
