The air inside a room is at a temperature of 65°F and has a mixing ratio of 5.2 g/kg? (a) What is the relative humidity?

(b) What is the dew point?

(c) If the mixing ratio remains the same, but the temperature of the room increases to 80°F, what is the new relative humidity?

39%

40⁰f

23.31%

Explanation:

Temperature = 65⁰f

U = mixing ratio = 5.2g/kg

Us = The corresponding Saturated ratio at 65⁰f is = 13.2

We find Relative humidity at 65⁰f

= U/Us

= 5.2/13.2

= 0.39x100

= 39%

2. The dew point was calculated using a dew point calculator the result was 40⁰f

3. If temperature = 80⁰f

Saturated ratio value = 22.3

= 5.2/22.3

= 0.2331 x 100

= 23.31%
