      What is a Psychrometer?

      A psychrometer is a type of hygrometer and is used exclusively to determine the relative humidity or moisture content in the air. Psychrometers represent an older humidity measurement form and electronic sensors that depend on changes in electrical resistance and capacitance rather than condensation temperature have widely replaced them. However, psychrometers are still found in

    • Air Exchangers

      Air Exchangers

      An air exchanger is a device that transfers stale air from inside a home to outside, and fresh air from outside to the inside. Air exchangers are often large and built directly into a home’s foundation in order to provide maximum fresh air levels at all times. This is important because indoor air is often

    • How Hurricanes Form

      How Hurricanes Form

      Hurricanes are caused by immense low pressured formed over the warm oceans in the summer and early fall months. With this low pressure, water vapor is evaporated off of the ocean surface. This water vapor releases the latent heat of condensation which causes all of the water to begin forming into clouds. This condensation forms

    • The Coriolis Effect

      The Coriolis Effect

      The Coriolis effect is the tendency for a moving body that is on or above the Earth’s surface to drift sideways from its intended course due to the Earth’s rotation. The direction of drift is to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is because the Earth’s

    • What Are Air Scrubbers?

      What Are Air Scrubbers?

      An air scrubber is a device that removes particles, gases, or chemicals from the air in a specific area. Air scrubbers are very important in some industries as workers are frequently exposed to harmful substances. Most air scrubbers are made for a specific type of air purification but some are made to handle particles, gases,

    • What Causes Lightning?

      What Causes Lightning?

      Lightning can be described as a massive discharge of electrical energy that can reach the speed of 130,000 mph and can exceed temperatures of 30,000 degrees Celsius. Although we know a lot about this phenomenon, it is still unclear how and why lightning forms. We will mention some of the theories on how lightning is

    • Air Circulators

      Air Circulators

      An air circulator is basically a fan. Although the term “air circulator” most often refers to an industrial fan that is used in a warehouse, factory, or office building, it can also refer to a regular household fan. Air circulators also refer to air conditioning units and other types of air cooling devices. They are

    • What Causes Earthquakes?

      What Causes Earthquakes?

      An earthquake is caused when two blocks or plates of the Earth slip past each other in the lateral, vertical, or a combination of directions in a sudden manner. Due to the large pressures that develop between the Earth’s plates along fault lines at the Earth’s surface, one of the bodies will eventually give way.

    • What Causes Evaporation?

      What Causes Evaporation?

      When the Earth begins to get too hot, the water increases in temperature. As the water continues to get hotter, it begins to undergo a phase change in which water turns to gas. The water droplets turn into water vapor because the temperature has caused the individual water molecules to speed up considerably. This process

    • Hot Water Circulators

      Hot Water Circulators

      A hot water circulator (circulator pump) is a device that circulates hot water through a house’s pipes so that hot water is always instantly available. In traditional one-way plumbing systems, water is run through a hot water heater and directed through the pipes towards the taps whenever a tap is turned on. When a tap
