Why Measure Moisture &Humidity?

Human beings as well as animals all like to live in certain humidity environment. Humans are best suited to and feel most comfortable at certain humidity and temperatures; excessively high or low humidity or temperatures cause discomfort.

As most materials are hygroscopic, their water content always tries to reach equilibrium with the surrounding relative humidity. Thus each material has its own ideal storage humidity which should be maintained. Too dry or too humid conditions could ruin the material.

In many production processes, the measurement and adjustment of humidity is extremely important for sustaining the high quality of products and the correct level of energy consumption. The right humidity makes it possible to optimize energy consumption and improve end product quality as well as product yield.

At low humidity cases, static electricity increases. This can be crucial in the chemical industry where dry powdery material is handled, to avert environ explosions caused by static electricity in extreme cases.

Humidity always plays important role in industrial corrosion, either from environment or pipeline. Keeping certain humidity is the most popular industry project.

 

PSYCHROMETRICS & MOISTURE

MOISTURE measurements involve different terms and units.

Moisture terms and units all fall under the area of psychro-metrics, the study of water vapor concentration in air as a function of temperature and pressure. Selecting a moisture term depends on the application at hand.

Dew points and frost points are often used when the dryness of the gas is important, (moisture condensation from gas at low process temperatures must be avoided). Dew point is also used as an indicator of water vapor in high temperature processes, such as industrial drying.

Mixing ratios, volume percent, and specific humidity are usually used when water vapor is either an impurity or a defined component of a process gas mixture used in manufacturing. Mixing ratios are also used, like dew point, in industrial drying.

Relative humidity is most commonly used in HVAC applications where it directly impacts human comfort and indoor air quality issues. Relative humidity is also of interest to process control personnel as low RH can cause brittleness and static electricity problems, while high RH can cause swelling and clumping regardless of temperature.

 

PSYCHROMETRICS deals with the thermodynamic properties of moist gases while the term Humidity simply refers to the presence of water vapor in air or other carrier gas.

Psychrometrics concerns mixtures of water vapor and dry air. Much of it also applies to other carrier gases since the thermo-dynamic characteristics of water vapor are fairly independent of the carrier gas. In addition, as the composition of atmospheric air is fairly constant, dry air is treated as a homogeneous gas with a molecular weight of 28.9645. The molecular weight of water is 18.01528.

 

WATER VAPOR PRESSURE: When a mixture of air and water vapor is in equilibrium with liquid water or with ice, it is considered to be saturated (RH J100%).
