Part A: calculating relative humidity from water vapor content
1. Use data table 1 to record your measurements
2. Relative humidity is the ratio of the air’s water vapor content to its water vapor capacity at a given temperature. Relative humidity is expressed as a percent
Relative humidity(%) = water vapor content / Water vapor capacity*100%
3. At 25*C the water vapor capacity is 20g/kg. Use this information to complete Data Table 1.
(I have a picture for it)
Part B: Determining relative humidity using a psychrometer
4. A psychrometer consists of two thermometers - a wet bulb thermometer and a dry bulb thermometer. The wet bulb thermometer has a cloth wick that is edgy with water and sun for about 1 minute. Relative humidity is determined by calculating temperature and the wet bulb temperature and using data table 2. For example, suppose a dry bulb temperature is measured as 20*C and a wet bulb temperature at 14*C. Read the relative humidity from Data Table 2.
(I have the picture for data table 2 also)
I have another question and it’s basically to calculate the difference between the dray and wet bulb temperatures and relative humidity of the air outside inside the Data Table 3
(And I also do have a picture for that one)
But yea if you can answer this, it would mean a lot.
