  • Humidity Sensors - 2853 Words
    Humidity Sensors Humidity Humidity is defined as the water vapor content in air or other gases. Humidity is usually measured in terms of absolute humidity (the ratio of the mass of water vapor to the volume of air or gas), dew point (the temperature and pressure at which a gas begins to condense into a liquid), and relative humidity, or RH (the ratio of the moisture content of air compared to the saturated moisture level at the same temperature or pressure). Thermal conductivity humidity...

    Relative Humidity Lab 1. Yes, our relative humidity was different for the two locations because the temperature in the building was lower than the temperature outside. 2. The psychrometer has a "sock" on the bulb of the thermometer. You get the sock wet and twirl the thermometer around for 30 seconds. If the temperature dropped then you spin it again for 15 seconds. Then you subtract the temperature of the psychrometer from the starting temperature and that is the difference. Then you must...

    Abstract The phenomenon of evaporative cooling is a common process in nature, whose applications for cooling air are being used since the ancient years. In fact, it meets this objective with a low energy consumption, being compared to the primary energy consumption of other alternatives for cooling, as it is simply based in the phenomenon of reducing the air temperature by evaporating water on it. This process can be an interesting alternative to conventional systems in these applications where...

    1. Is a temperature inversion more likely to form on a calm or a windy night? Why? A temperature inversion is most likely to form on a calm night. Windy nights are not ideal for an inversion to occur since an inversion is considered a stable layer of atmosphere as well as due to the wind mixing the air to even out the density, remembering cold air is denser than warm air so it will flow downhill and pool in a valley. 2. What are the various methods used to protect sensitive crops from...

  • Large Cities Have Their Own Climatic Conditions
    Large cities have their own climatic conditions. To what extent is this true? (40 marks) Large cities have their own climatic conditions and can be referred to as having a micro-climate. Micro-climates are small scale variations in temperature, precipitation, humidity, wind speed and evaporation that occur in an environment. This would therefore suggest that the statement is in fact true. Large cities create their own climate and weather which is known as the ‘urban climate dome’ within which...

    The term ‘urban heat island’ refers to the localized increase in temperature associated with an urban area. The UHI is an example of unintentional climate modification when urbanization changes the characteristics of the earth’s surface and atmosphere. It was observed that the UHI effect might result in minimum urban temperatures being 5-6° greater than the surrounding countryside.

    a. From 23 degrees to 28 degrees the slope of the line increases and shows a slight curve. The rate of evaporation increases with temperature since transpiration is a cooling mechanism to release heat. More stomata open as temperature increases as this allows a faster transpiration rate. Although, at much higher temperatures, plants close stomata to prevent excess water loss. b. The increasing humidity causes reduced transpiration rates. This is because atmosphere is saturated with water...

The amount of water vapor any mass of air can contain depends on the temperature of that air. The warmer the air is, the more water it can hold. A low relative humidity means that the air is dry and could hold a lot more moisture at that temperature. For example, at 20 degrees C (68 degrees F), a cubic meter of air can hold a maximum of 18 grams of water. At...
