The table below shows the saturation vapour pressure against temperature in a certain town. If the vapour pressure in this town at 20oC is 10mmHg, what is the relative humidity?
| T(oC) | 0 | 5 | 10 | 15 | 20 | 40 | 60 |
| S.V.P (mmHg) | 4.58 | 6.51 | 8.94 | 12.67 | 17.50 | 55.10 | 149.00 |
170.0%
57.0%
17.5%
10.0%
Correct answer is B
Explanation
R.H = Partial Pressure of Water Vapour Presentx100_1S.V.P at temperature of atmosphere
= _10x100_117.50
= 57.14%
