Put another way, if measured dew-point temperatures were being used to infer mainstream vapor mole fractions (y1,e), neglect of this Soret enrichment effect would lead to an over-estimate by a factor of ca. 2.5.
Industry practitioners often rely on measuring the dew point (among other phase behavior properties) using laboratory experiments.
The difference between exterior and interior humidities (measured both as dew point and relative humidity) varied substantially, possibly reflecting differences in the ventilation between houses.
A Lascar datalogger was used to measure indoor temperature, dew point, and humidity in the school 1 classroom (from 7 38 am to 15 38 pm) March 15 19, 2010 and from March 22 26, 2010 in the classroom for school 2 (from 7 34 am to 14 34 pm) in Yaoundé.
Water content of the effluent air was measured using high precision dew point mirrors (Model 473, RH systems, Albuquerque, NM, USA).
3 This relationship was based on the analyses of 12 European cities over the 1990s, using the daily maximum apparent temperature (AT), where AT is a combination of the measured temperature and the dew point temperature: where T is the air temperature and DT the dew point temperature, which can be derived from temperature and relative humidity.
Another measure is the dew point, the temperature at which vapor in the air condenses into water.
Based on the resulting 3D spatio-thermal models and by measuring the reflected and dew point temperatures, the actual R-values of building assemblies are calculated, and the condensation issues are analyzed.
Currently, the following sets of sensors are being utilized: Temperature, Humidity and Dew Point are measured using the Sensirion SHT11 (2012) humidity and temperature sensor.
Water potentials were measured using an HR-33T Dew Point Microvoltmeter (Wescor Inc., Logan, UT, USA).
