Pittsburgh Gasometer Explosion
The Pittsburgh gasometer explosion, or Equitable Gas explosion, was an accident that took place in Pittsburgh, Pennsylvania on the morning of November 14, 1927. A huge cylindrical gasometer A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressu ..., the largest in the world at that time at , developed a leak, and repairmen were sent to fix it. The exact cause of the explosion is not known, but some of those repairing the leak were using acetylene torches. There was a loud explosion, and three gasometers at the site exploded. A "dense mass of dust and smoke" rose from the ruins before igniting into a ball of fire reported as 100 feet in diameter, which rose further before burning out at a height of 1000 feet. Most buildings within a radius of half a mile were damaged, with windows being broke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Explosion (715
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colourless gas invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehe ...

Pennsylvania
Pennsylvania (; ( Pennsylvania Dutch: )), officially the Commonwealth of Pennsylvania, is a state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States. It borders Delaware to its southeast, Maryland to its south, West Virginia to its southwest, Ohio to its west, Lake Erie and the Canadian province of Ontario to its northwest, New York to its north, and the Delaware River and New Jersey to its east. Pennsylvania is the fifth-most populous state in the nation with over 13 million residents as of 2020. It is the 33rd-largest state by area and ranks ninth among all states in population density. The southeastern Delaware Valley metropolitan area comprises and surrounds Philadelphia, the state's largest and nation's sixth most populous city. Another 2.37 million reside in Greater Pittsburgh in the southwest, centered around Pittsburgh, the state's second-largest and Western Pennsylvania's largest city. The state's su ...

National Weather Service
The National Weather Service (NWS) is an Government agency, agency of the Federal government of the United States, United States federal government that is tasked with providing weather forecasts, warnings of hazardous weather, and other weather-related products to organizations and the public for the purposes of protection, safety, and general information. It is a part of the National Oceanic and Atmospheric Administration (NOAA) branch of the United States Department of Commerce, Department of Commerce, and is headquartered in Silver Spring, Maryland, Silver Spring, Maryland, within the Washington metropolitan area. The agency was known as the United States Weather Bureau from 1890 until it adopted its current name in 1970. The NWS performs its primary task through a collection of national and regional centers, and 122 local List of National Weather Service Weather Forecast Offices, Weather Forecast Offices (WFOs).

Gasometer
A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap. Typical volumes for large gas holders are about , with diameter structures. Gas holders now tend to be used for balancing purposes to ensure that gas pipes can be operated within a safe range of pressures, rather than for actually storing gas for later use. Etymology Antoine Lavoisier devised the first gas holder, which he called a ''gazomètre'', to assist his work in pneumatic chemistry. It enabled him to weigh the gas in a pneumatic trough with the precision he required. He published his ''Traité Élémentaire de Chimie'' in 1789. James Watt Junior collaborated with Thomas Beddoes in constructing the pneumatic apparatus, a shortlived piece of medical equipment that incorporated a ''gazo ...

Pittsburgh Magazine
Pittsburgh Magazine is a lifestyle magazine covering the Pittsburgh metropolitan area. It hosts an annual "40 Under 40" featuring prominent young Pittsburghers. It's known for listicles including Pittsburgh's 25 Best Restaurants, Best of the 'Burgh, Top Doctors, Top Dentists and annual City Guide. It is a member of the City and Regional Magazine Association (CRMA). About The magazine was purchased in 1970 by WQED, who used the magazine as part of its pledge drives. By 1978, it was still losing money, but it had gained tax-exempt status through WQED. Allies of Richard Mellon Scaife, the owner of the rival ''Pittsburgh Tribune-Review'' and the ''Pittsburgher'', investigated the financial status, with a possible eye toward challenging the tax-exempt status. In 1983, the magazine was drawn into a battle between staff members regarding WQED's involvement with Nancy Reagan's anti-drug campaign. In 1990, the magazine was the subject of a libel lawsuit brought by two police officers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explosions In 1927
An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes Explosions can occur in nature due to a large influx of energy. Most natural explosions arise from volcanic or stellar processes of various sorts. Explosive volcanic eruptions occur when magma rises from below, it has very dissolved gas in it. The reduction of pressure as the magma rises and causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur outside of Earth in the universe in ...

History Of Pittsburgh
The history of Pittsburgh began with centuries of Native American civilization in the modern Pittsburgh region, known as "Dionde:gâ'" in the Seneca language. Eventually, European explorers encountered the strategic confluence where the Allegheny and Monongahela Rivers meet to form the Ohio, which leads to the Mississippi River. The area became a battleground when France and Great Britain fought for control in the 1750s. When the British were victorious, the French ceded control of territories east of the Mississippi. Following American independence in 1783, the village around Fort Pitt continued to grow. The region saw the short-lived Whiskey Rebellion, when farmers rebelled against federal taxes on whiskey. The War of 1812 cut off the supply of British goods, stimulating American manufacture. By 1815, Pittsburgh was producing large quantities of iron, brass, tin, and glass products. By the 1840s, Pittsburgh had grown to be one of the largest cities west of the Allegheny Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
