Relative humidity is generally expressed as percentage. Vp dry and Vp wet are the vapor pressure of the dry and wet streams. The presence of water vapour in the atmosphere is a vital factor for weather conditions of a particular region.
It is aggregate of atmospheric conditions involving heat, moisture and air movement. Kuala Lumpur and Singapore have very high humidity all year round because of their proximity to water bodies and the equator and overcast weather; despite sunshine, perfectly clear days are rare in these locations and it is often misty.
The higher the aridity, temperature and velocity of winds, the higher the rate and amount of evaporation because dry air with high temperature is capable of retaining more moisture vapour as dry air requires more time and moisture to become saturated.
In addition, the chitosan film is oxidized. In the US, the midwest and Mississippi have recorded dew point temperatures above The principle behind an effective operation is based on evanescent scattering and absorption of wave.
Another type of a fiber optic sensor for humidity uses the silica sol-gel film.

Goggy Davidowitz, an entomologist at the University of Arizona explains that smaller bugs are more likely to dehydrate because they have a larger surface area relative to their whole body size.
It is usually expressed as fine, fair, foggy, cloudy, rainy, sunny or windy weather. Maybe because the capacity of the water vapor was a factor and the temperature outside had an impact.
Inside the chamber, there is a circuit that regulates and stabilizes the amount of heat and therefore the temperatures. The king told the eagle that he is ready to pay any price in return for saving the pigeon. The process of conversion of vapour into liquid water and solid form ice, snow, frost is called condensation.
It may be mentioned that water occurs in three states viz. It remains as it is so that it can form the dry stream. Very high relative humidity leads to: Fiber sensors are very receptive to restrictions that are capable of modifying either the frequency, intensity, or the segment of light that travels through the fiber.Humidity is measured by the amount of vapor in the air not by the total amount of vapor and liquid.
Global climate is flexible by humidity and water vapor which are both very important to the global climate. Humidity, water vapor is important in the global climate. Air quality inside and out are.
