>>Anyone know the formula for this? Haven't been able to find one on the net that works out when you run the numbers through a psychrometric chart. Any help appreciated!
The experimental values of Saturated vapour pressure at different temperatures are given in the tables.
The formula for calculating dew point is based on the relationship between temperature, relative humidity, and the saturation vapor pressure of water in the air. The exact formula varies depending on the units used for temperature and humidity, but it typically involves taking the natural logarithm of the RH, multiplying it by a constant, and then adding the temperature in degrees Celsius.
The dew point temperature is the temperature at which the air would need to cool in order for the relative humidity to reach 100% and for water vapor to start condensing into liquid water. It is an important measure of the amount of moisture in the air, as well as a factor in predicting potential fog formation, frost, and other weather conditions.
No, the dew point can never be higher than the temperature. This is because the dew point is the temperature at which water vapor in the air starts to condense into liquid water, so it cannot be higher than the actual temperature.
The higher the air temperature, the more water vapor it can hold and the higher the dew point will be. This is because warm air has a higher capacity for holding water vapor than cold air. So as the temperature increases, the dew point will also increase.
No, the dew point and humidity are two different measures of moisture in the air. Humidity is a measure of the amount of water vapor in the air relative to its maximum capacity at a given temperature, while the dew point is the temperature at which the air would need to cool for the relative humidity to reach 100%. They are related, but not the same.
