psychrometry


Also found in: Dictionary, Encyclopedia, Wikipedia.

psy·chrom·e·try

(sī-krom'ĕ-trē),
The calculation of relative humidity and water vapor pressures from wet and dry bulb temperatures and barometric pressure; whereas relative humidity is the value ordinarily employed, the vapor pressure is the measurement of physiologic significance.
Synonym(s): hygrometry
[psychro- + G. metron, measure]

The drying temperatures adopted in the dryer were: 40, 50, 60 and 70 [degrees]C, under controlled conditions, with relative humidity values of 20.55, 12.74, 9.23 and 4.96%, respectively, obtained through basic principles of psychrometry. At all temperatures, drying was interrupted when the leaves reached 0.11 [+ or -] 0.005 decimal (b.s), according to Goneli et al.
Insurers and consumers may benefit from hiring professionals who understand the use of psychrometry, the scientific standard for the monitoring and control of water damage.
The final documentation includes a psychrometry log, a moisture content log, a drying calculation work sheet, and a dehumidifier requirement work sheet.

Oosterhuis has taught eight different courses including Agricultural Botany, Plant Production Science, Fiber and Oil Seeds, Cotton Production, Crop Physiology, Thermocouple Psychrometry, Methodology in Agronomic Research, and numerous cotton extension courses.
Today, restoration companies use the techniques of psychrometry (the science of drying) and state-of-the-art equipment that can sharply reduce the severity of claims.
Briefly, osmotic potentials ([[Psi].sub.[Pi]]) of frozen thawed tissues were determined by thermocouple psychrometry in two (maize and barley) or four (rice) leaf segments (6-mm length from the leaf expansion zone) per leaf cutter chamber and a 3-h equilibration period at 27 [degrees] C in a water bath.
Although not much larger than a business card, the new Digital Psychrometric Calculator from Dri-Eaz contains practical functions making it easier for restorers to consistently incorporate the science of psychrometry into their everyday work.
