Heat exchanger paint: Relationship between dew point and humidity
Thread Content
People often determine the absolute and relative humidity of air by measuring the dew point; therefore, the dew point is also a way of indicating air humidity. When the temperature of the air at a certain air pressure is 20°C and the dew point is 12°C, it is possible to find from the table that the saturated vapor pressure at 20°C is 17.54 mmHg, while the saturated vapor pressure at 12°C is 10.52 mmHg. Then at this time: the relative humidity of the air is B = (10.52/17.54) × 100% = 60%. Using this method to determine air humidity has great practical value. But a crucial point here is: how to choose the instruments and methods for measuring dew point?
