2.1.1 Theory of Relative Humidity Relative humidity is the relationship between the actual water vapor pressure and the maximum possible water vapor pressure. As stated by PAGASA (Philippine Atmospheric‚ Geophysical and Astronomical Services Administration) “Due to high temperature and the surrounding bodies of water‚ the Philippines have a high relative humidity. The average monthly relative humidity varies between 71 percent in March and 85 percent in September”. Relative humidity contributes

OBSIDIAN HYDRATION There are two ways of Obsidian Hydration. One is to determine if the artifact is older or younger as the other is a calendar date of AD/BC being used. The decision of which one to use is relative or absolute dating depends on the environment’s condition. The dating of Obsidian Hydration artifacts‚ which is based on the fact that a freshly made surface of obsidian will absorb water from it’s surroundings to form a measurable hydration layer. For example‚ cracking of the lava

Approaches to Humidity Control Humidity control in a conditioned space is done by controlling the amount of water vapor present in the air in the space. When relative humidity at the desired temperature set-point is too high‚ dehumidification is required to reduce the amount of water vapor in the air for humidity control. Similarly‚ when relative humidity at the desired

They have many similarities but there has to be something different about them that helps you choose a decision but you cant find it. Is it the environment that surrounds each of the schools.

Before completing this lab‚ one must understand that “all air has some moisture in it‚ but how wet the air feels depends not just on the amount of moisture but also the temperature of the air” (Lab Intro Given). In the meteorology career‚ terms such as “dew point and “relative humidity” are used. The following

Aerodynamics Parachutes work on the principles of gravity and air resistance and in effect‚ terminal velocity. Air resistance (air friction) Air resistance is an upward force exerted on a body while it is in the air and is the result of air molecules that come in contact with the surface of the falling object. This force attempts to counteract gravity and other downwards forces influencing a body. The amount of air resistance encountered by an object is dependent on two factors: speed of the object

Hypothesis: ‘If the sector size is the increase‚ then the terminal velocity will decrease.’ The reason is that if the sector size is bigger‚ the surface area of the cone will become smaller. If the surface area is smaller‚ than the friction will be less‚ so there will be less terminal velocity. Variables Table: Variables

A setup was developed to monitor the mass loss of mush-rooms under various surrounding temperatures (4‚ 10 and 16 ° C) and relative humidity (76%‚ 86% and 96%). Mass loss of whole buttonmushrooms ( Agaricous bisporous ) was measured and transpiration rates were calculated at all the experimental conditions tested.
