The percentage of relative humidity is often mentioned in weather forecast.
If p represents the absolute humidity of air at a certain temperature, p represents the saturated pressure of water vapor at the same temperature, and b represents the relative humidity, then
The water vapor saturation pressure of water at a certain temperature can be found from the table below. Therefore, knowing the absolute humidity, we can calculate the relative humidity; Conversely, knowing the relative humidity can also calculate the absolute humidity.
If the absolute humidity of air is p=800Pa, when the temperature is 20℃, the relative humidity of air is
When the temperature is 65438 00℃ C, the relative humidity of the air.
In a living room, the suitable relative humidity is about 60%, and the most suitable relative humidity for heading and flowering of rice is 70% ~ 80%.
