Mass flow is derived from the volume flow result to which a density correction is applied.
2.
Air density corrections need to be taken into account for centrifugal fans that are specified for continuous operation at higher temperatures.
3.
To get the actual power at, the designer would have to divide the power at standard conditions by the air density correction factor.
4.
To get the actual horsepower at 200�F, the designer would have to divide the brake horsepower at standard conditions by the air density correction factor.
5.
The AGA 7 calculation itself is a simple ratio and is, in essence, a density correction approach to translating the volume or rate of gas at flowing conditions to a volume or rate at base conditions.
6.
When a centrifugal fan is specified for a given CFM and static pressure at conditions other than standard, an air density correction factor must be applied to select the proper size fan to meet the new condition.
7.
To get the actual pressure required at, the designer would have to multiply the pressure at standard conditions by an air density correction factor of 1.25 ( i . e ., 1.0 / 0.8 ) to get the system to operate correctly.
8.
To get the actual pressure required at 200�F, the designer would have to multiply the pressure at standard conditions by an air density correction factor of 1.25 ( i . e ., 1.0 / 0.80 ) to get the system to operate correctly.
