barometric pressure cycles
Barometric pressure changes can induce airflow in an open borehole or well screened in the vadose zone, thereby ventilating the soil surrounding the borehole. This paper presents an analytic model of the induced airflow and compares the predictions of the model with experimental measurements. This model may be useful for the design of passive soil vapor extraction as applied to the remediation ...
متن کاملRemoval of barometric pressure effects and earth tides from observed water levels.
The effects of barometric pressure and earth tide changes are often observed in ground water level measurements. These disturbances can make aquifer test interpretation difficult by masking the small changes induced by aquifer testing at late times and great distances. A computer utility is now available that automatically removes the effects of barometric pressure and earth tides from water le...
متن کاملAN1326, Barometric Pressure Measurement Using Semiconductor Pressure Sensors
The most recent advances in silicon micromachining technology have given rise to a variety of low-cost pressure sensor applications and solutions. Certain applications had previously been hindered by the high-cost, large size, and overall reliability limitations of electromechanical pressure sensing devices. Furthermore, the integration of on-chip temperature compensation and calibration has al...
متن کاملBarometric pressure, emergency psychiatric visits, and violent acts.
BACKGROUND Associations between human behaviour and psychiatric decompensation and weather variables have been inconsistent. OBJECTIVES We studied the association of certain weather variables (specifically, humidity, wind speed, and barometric pressure) with emergent psychiatric presentations, psychiatric admissions, incidence of violent crimes, and suicides in a metropolitan area. METHOD W...
