For example, in a Trane Engineers Bulletin that discusses fan systems as applied to VAV systems, they show a generic range of fan static pressures ranging from 1.5 to 3.15 in.
Kistler says the high sensitivity of the unique PiezoStar crystal it has developed , much higher than that possible with quartz, allows small pressure fluctuations which are superimposed on static pressures to be measured with exceptional resolution.
For the add-on ERY unit in the example (System D), the fan efficiency and internal static pressures are unknown as the ERV brake horsepower is cataloged against external static pressure.
Many industrial pressure sensors are used to make dynamic measurements, yet have often only been calibrated using static pressures - the pressures exerted by a still liquid or gas.
Reducing the output to 1.5MW for four hours reduces the mass of the piston to 1,100 tonnes, but doesn't reduce static pressures. With a smaller piston, it might be more practical to suspend it from a pulley and allow it to fall down an air-filled shaft.
Complementing the accelerometer is the 176M03 charge output pressure sensor, developed for measurement of dynamic pressure in the presence of high static pressures. Turbine applications are often at 300 psi static with dynamic pressures up to 5 psi.
Given the three possible adjustments, a study was undertaken to determine the effects varied belt speeds, static pressures and zone temperatures have on the peak temperature, time above liquidus (TAL) and temperature uniformity of a 100 and 230 g populated surface mount board.
Centrifugal compressor performance, in terms of energy coefficient across the impeller, derived from inlet nozzle static and delivery static pressures measured for all four configurations is presented.
In response to market demand for an accurate, easy-to-use differential pressure standard at high static pressures, GE Sensing has introduced the Ruska Model 2482 differential piston gauge.
The cyclone's rubberized interior is abrasion resistant, and reinforced housing is designed for vacuum applications with static pressures of 50" w.g.
Typically, IBC ducting has to withstand static pressures and vacuum of up to 50 in.
The centrifugal blower is suited for applications requiring horizontal air intake or for systems with external static pressures in excess of 8" wg.
