6 Dew Point - Essay ExampleThe dew pull pop out is a recommended indicator of the developed water vapor content of the air because variations in atmospheric pressure at the earths surface are preferably minimal.Dew point is deliberate by an instrument called a Dew Point Meter. These instruments have a polished metal mirror which is cooled as air passes over it (Hens 2007). Essentially, the dew point is determined by finding out the temperature at which dew forms. These manual devices may also be used to standardize other types of instruments that measure humidity. Moreover, automatic sensors may be utilize in a control loop where a humidifier or a dehumidifier is used to manage the dew point of the air in a building or in smaller spaces used for manufacturing processes (Hens, 2007).A high dew point indicates that the air has high water vapor content while a low dew point indicates that the air has low water vapor content. When the air has high water vapor content and, correspon dingly, a high dew point, it is said that the air is humid and masses are most likely uncomfortable with such situations. This is because a persons body is designed to use the evaporation of sweat to cool itself down during warm temperatures. However, evaporation largely depends on how much moisture the air already contains and how much more it can hold (Sills 2010). Thus, if the air is already saturated, a persons sweat will no longer evaporate and so that person ends up sweating profusely. At certain cases where dew point is quite elevated, people suffering from respiratory ailments like asthma may even be in grave danger.The dew point is considered to be an important indicator of the air travels condition. It affects the living conditions of humans and animals alike and thus, it must be monitored closely using accurate instruments in order to provide necessary and appropriate advice to those who energy need
