Question on: JAMB Physics - 2024
If the S.V.P of water vapour was 13.5 mmHg at 33ºC and 7.3 mmHg at 7ºC, find the percentage relative humidity on a day when the average air temperature was 33ºC and dew point was 7ºC.
A
55%
B
60%
C
54%
D
51%

Correct Option: C
Here's how to solve the problem:
- Understand the concepts: Saturated Vapor Pressure (SVP) is the pressure when air is saturated. Dew point is the temperature at which air becomes saturated. Relative Humidity (RH) = (actual vapor pressure / SVP at current temperature) x 100%.
- Given: SVP at 33ºC = 13.5 mmHg, SVP at 7ºC = 7.3 mmHg (actual vapor pressure at dew point).
- Calculate RH: RH = (7.3 / 13.5) x 100 ≈ 54%
