High Accuracy Acoustic Relative Humidity Measurement in Duct Flow with Air
An acoustic relative humidity sensor for air-steam mixtures in duct flow is designed and tested. Theory, construction, calibration, considerations on dynamic response and results are presented. The measurement device is capable of measuring line averaged values of gas velocity, temperature and relative humidity (RH) instantaneously, by applying two ultrasonic transducers and an array of four te...
متن کاملSimplifying Humidity Measurement with Single-Chip Relative Humidity and Temperature Sensor ICs
Humidity sensing technology is critical to a wide range of applications, including HVAC and refrigeration, healthcare equipment, such as CPAP machines and ventilators, asset tracking and storage devices for the food and pharmaceutical industries, industrial control systems, meteorological instruments, automotive climate control and defogging, and mobile computing devices. Despite its pervasive ...
متن کاملAir Temperature and Relative Humidity Study: Torgac Cave, New Mexico
Torgac Cave, located in south-central New Mexico is remarkable for at least three reasons: its extraordinary gypsum speleothems, its large bat population, and the unusually cold temperatures within the cave. It has been proposed that the presence of the bats and the speleothems may be related to the anomalous temperatures observed in the cave. This paper reports the results of a five week study...
متن کاملThe Lethal Effect of Relative Humidity on Air-borne Bacteria
The viability of pneumococcus, Type I, sprayed into the atmosphere from a liquid suspension was measured as a function of the relative humidity. When broth, saliva, or 0.5 per cent saline solution is employed as the suspending medium, a very high mortality rate is observed at relative humidities in the vicinity of 50 per cent. However, at humidities above or below this value the microorganisms ...
متن کاملThe dichotomy of relative humidity on indoor air quality.
Dry and irritated mucous membranes of the eyes and airways are common symptoms reported in office-like environments. Earlier studies suggested that indoor pollutants were responsible. We have re-evaluated, by review of the literature, how low relative humidity (RH) may influence the immediately perceived indoor air quality (IAQ), including odour, and cause irritation symptoms (i.e. longer-term ...
