Air - Volume vs. Temperature
Air volume vs. temperature correction factor compared to Normal Air Conditions.
The volume correction factor of air at higher or lower temperatures than normal air:
| Temperature | Volume Correction Factor | |
|---|---|---|
| (oC) | (oF) | |
| -46 | -50 | 0.77 |
| -40 | -40 | 0.79 |
| -34 | -30 | 0.81 |
| -28 | -20 | 0.83 |
| -23 | -10 | 0.85 |
| -18 | 0 | 0.87 |
| -9 | 10 | 0.89 |
| -5 | 20 | 0.91 |
| -1 | 30 | 0.93 |
| 4 | 40 | 0.94 |
| 10 | 50 | 0.96 |
| 18 | 60 | 0.98 |
| 22 | 70 | 1.00 |
| 27 | 80 | 1.02 |
| 32 | 90 | 1.04 |
| 38 | 100 | 1.06 |
| 43 | 110 | 1.08 |
| 49 | 120 | 1.10 |
Example - Volume Change when Air is Heated
2 m3 of air is heated from 22oC to 43oC. The volume correction factor is 1.08 and the new volume can be calculated as
(2 m3) 1.08 = 2.16 m3
