A room has relative humidity of #20%# at #20# degrees Celsius with dimensions #3m \times 3m \times 2.7m#. Determine the amount of water vapour in grams and liters that must be added to the air of the room in order to raise the relative humidity to #60%#?
1 Answer
Explanation:
The information that I am using to work this problem is obtained from this reference on Relative Humidity .
Compute the volume of the room:
Using the equation:
and, at
Please observe that the equation for relative humidity is linear, therefore, multiplying the relative humidity by 3 will multiply the actual vapor density by 3, which is the same as adding twice the original amount:
We can compute the number of grams to be added by multiplying the above by the volume of the room:
To convert grams of water to liters of water we multiply by
