Air - Volume vs. Temperature
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
