To reduce lab ventilation energy costs, variable air volume ( VAV ) systems are employed, which reduce the volume of the air exhausted as the fume hood sash is closed.

While overall next-day air volume was up about 10 percent, the revenue generated per piece shipped was down because more letters were being delivered than packages, which cost more to send.
43.
The presence of the immune-system cells, neutrophiles and lymphocytes, indicated the stress on the lungs even though traditional lung tests, such as measuring the exhaled air volume, showed no abnormal variation.

Being both portable and able to generate wind speeds of between and air volumes of 14 m 3 per minute, the leaf blower has many potential uses in amateur construction projects.
45.
The hazard in a crawl space is increased because there is less air volume in such spaces, and the air gets colder than in a basement that has more air volume.

Since RAV hoods have restricted sash movement and reduced air volume, these hoods are less flexible in what they can be used for and can only be used for certain tasks.
48.
If air density increases due to pressure increase or temperature drop, but the air volume remains constant, the denser air will remove more heat from the wire indicating a higher mass airflow.
49.
So, many customers will be able to get guaranteed " overnight " service without paying the premium for " Next Day Air " service, which could dent the more profitable air volume.

A significant increase in intake air volume will only occur in an engine where the factory intake piping was designed with baffles and other sound absorbing materials ( rubber, etc . ).
