Question

Air temperature at 20°C can hold 14 grams of water vapor. If an air mass is 20°C and has seven grams of water vapor, what would its relative humidity be?

Answer 1

relative humidity fro 14 gm water vapor is 100%

relative humidity fro 7 gm water vapor is 50%

Step-by-step explanation:

Given data:

Air temperature of 20 degree celcius can sustain 14 gram water vapor

from table - saturation mixing ration

saturation mixing ration for air temperature at 20 degree celcius is 14g/kg

therefore relative humidity is
`= (14)/(14)*100 = 100`%

Air temperature of 20 degree celcius can sustain 7 gram water vapor

from table - saturation mixing ration

saturation mixing ration for air temperature at 20 degree celcius is 14g/kg

therefore relative humidity is
`= (7)/(14)*100 = 50`%
