[′dü ‚pȯint ‚presh·ər]
(chemical engineering)

For research, accurate experimentation, high-accuracy-real -moist-air-psychrometric modeling, conditions with higher pressures than 500 kPa or outside of the -80[degrees]C to 40[degrees]C (-112[degrees]F to 104[degrees]F) range, the one-part "full range" [[phi].sub.Real] definition is defined as the ratio of the actual water vapor partial pressure in moist air at the dew-point pressure and temperature to the reference-saturation-water-vapor-partial pressure at the dry-bulb pressure and temperature as represented by Equation 2.
