WebThe mean minimal FGF at the point of rebreathing was significantly lower in the Lack-Plus group than in the Lack group ( p <0.001) ( Table 2 ). The ETCO 2 level was significantly higher in the Lack-Plus group, and the FGF requirement was decreased by 18.7% for no rebreathing. The mean RR, arterial pressure, and SpO 2 value between the groups ... Web3 jul. 2009 · The Btu content of gas is measured by taking a sample and having it analyzed to determine its constituents of hydrocarbons. This is done periodically for each well, once or twice a year, since the hydrocarbon content of gas from a particular well usually does not change materially over time.
WebThe new clamp-on ultrasonic flow meter for gases not only provides measurements at high pressure gas flows but also down to atmospheric conditions even in steel pipes which was impossible until recently. The unit is available for permanent use in both safe and hazardous environments with rugged housings for Zones 1 and 2. WebThe only safe way to guarantee there is no confusion when using normal and standard flow rates is to state what conditions you are using, e.g. 314 standard m 3 /hr at 15 o C and …
