Relative humidity is a measure of the amount of moisture present in the air compared to the maximum amount of moisture the air can hold at a given temperature. It is expressed as a percentage. In order to determine the relative humidity in this scenario, we need to calculate the actual water vapor pressure and compare it to the saturation vapor pressure at the given temperature.
Given information:
- Barometer pressure: 1.03 bar
- Partial pressure of air: 1 bar
- Saturation partial pressure of water vapor: 0.05 bar
Calculating the actual water vapor pressure:
The actual water vapor pressure is the difference between the barometer pressure and the partial pressure of air. Therefore, the actual water vapor pressure can be calculated as follows:
Actual water vapor pressure = Barometer pressure - Partial pressure of air
Actual water vapor pressure = 1.03 bar - 1 bar
Actual water vapor pressure = 0.03 bar
Calculating the relative humidity:
The relative humidity can be calculated by dividing the actual water vapor pressure by the saturation vapor pressure and multiplying by 100.
Relative humidity = (Actual water vapor pressure / Saturation vapor pressure) * 100
Substituting the given values:
Relative humidity = (0.03 bar / 0.05 bar) * 100
Relative humidity = (0.6) * 100
Relative humidity = 60%
Therefore, the relative humidity in this scenario is 60%.
Given information:
- Barometer pressure: 1.03 bar
- Partial pressure of air: 1 bar
- Saturation partial pressure of water vapor: 0.05 bar
Calculating the actual water vapor pressure:
The actual water vapor pressure is the difference between the barometer pressure and the partial pressure of air. Therefore, the actual water vapor pressure can be calculated as follows:
Actual water vapor pressure = Barometer pressure - Partial pressure of air
Actual water vapor pressure = 1.03 bar - 1 bar
Actual water vapor pressure = 0.03 bar
Calculating the relative humidity:
The relative humidity can be calculated by dividing the actual water vapor pressure by the saturation vapor pressure and multiplying by 100.
Relative humidity = (Actual water vapor pressure / Saturation vapor pressure) * 100
Substituting the given values:
Relative humidity = (0.03 bar / 0.05 bar) * 100
Relative humidity = (0.6) * 100
Relative humidity = 60%
Therefore, the relative humidity in this scenario is 60%.
