2007 New York City Steam Explosion
On July 18, 2007, an explosion in Manhattan, New York City, sent a geyser of hot steam up from beneath a busy intersection, with a 40-story-high shower of mud and flying debris raining down on the crowded streets of Midtown Manhattan. It was caused by the failure of an 83-year-old, underground steam pipe near Grand Central Terminal, which exploded during the evening rush hour. 45 people were injured, and one woman died of a heart attack while fleeing. Initial fears that the cause was related to terrorism were quickly allayed by statements by mayor Michael Bloomberg and other officials shortly after the event. Background More than 12 similar Con Edison steam pipe explosions have occurred in New York City since 1987. One of the most significant events occurred near Gramercy Park in 1989, killing two Con Edison workers and one bystander, and causing damage of several million U.S. dollars. The utility eventually pleaded guilty to lying about asbestos contamination from that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lexington Avenue
Lexington Avenue, often colloquially abbreviated as "Lex", is an avenue on the East Side of the borough of Manhattan in New York City that carries southbound one-way traffic from East 131st Street to Gramercy Park at East 21st Street. Along its , 110-block route, Lexington Avenue runs through Harlem, Carnegie Hill, the Upper East Side, Midtown, and Murray Hill to a point of origin that is centered on Gramercy Park. South of Gramercy Park, the axis continues as Irving Place from 20th Street to East 14th Street. Lexington Avenue was not one of the streets included in the Commissioners' Plan of 1811 street grid, so the addresses for cross streets do not start at an even hundred number, as they do with avenues that were originally part of the plan. History Both Lexington Avenue and Irving Place began in 1832 when Samuel Ruggles, a lawyer and real-estate developer, petitioned the New York State Legislature to approve the creation of a new north–south avenue between the exist ...

New York City Steam System
The New York City steam systems include Con Edison, Con Edison's Steam Operations, and other smaller systems that provide steam to New York University and Columbia University. Many individual buildings in New York City, New York have their own steam systems. Con Edison's Steam Operations Con Edison's Steam Operations is a district heating system which carries steam from generating stations under the streets to heat and cool buildings and businesses in Manhattan. Some New York City, New York businesses and facilities also use steam for cleaning and disinfection. The New York Steam Company began providing service in lower Manhattan on March 3, 1882. Today, Consolidated Edison operates the largest commercial District heating, steam system in the world (larger than the next nine combined). The organization within Con Edison responsible for the system's operation, known as Steam Operations, provides steam service to over 1,700 commercial and residential customers in Manhattan fro ...

Steam Trap
A steam trap is a device used to discharge condensates and non-condensable gases with a negligible consumption or loss of live steam. Steam traps are nothing more than automatic valves. They open, close or modulate automatically. The three important functions of steam traps are: * Discharge condensate as soon as it is formed (unless it is desirable to use the sensible heat of the liquid condensate) * Have a negligible steam consumption (i.e. being energy efficient) * Have the capability of discharging air and other non-condensable gases. Basic operation The operation of a steam trap depends on the difference in properties between steam and condensate. Since liquid condensate has a much higher density than gaseous steam, it will tend to accumulate at the lowest possible point in the steam system. Steam properties such as density, latent heat, and saturation/boiling point are affected by pressure. Steam traps can be split into three main categories; Mechanical, Thermodynamic, and ...

Tow Truck
A tow truck (also called a wrecker, a breakdown truck, recovery vehicle or a breakdown lorry) is a truck used to move disabled, improperly parked, impounded, or otherwise indisposed motor vehicles. This may involve recovering a vehicle damaged in an accident, returning one to a drivable surface in a mishap or inclement weather, or towing or transporting one via flatbed to a repair shop or other location. A tow truck is distinct from a car carrier trailer, which is used to move multiple new or used vehicles simultaneously in routine transport operations. History Ferdinand Porsche of Austro-Daimler developed an artillery tractor for the Austro-Hungarian army in 1908, the M 08. One of the batch was constructed as a recovery vehicle for the others, with a large winch on the rear platform. The wrecker (with lifting jib) was invented in 1916 by Ernest Holmes Sr. of Chattanooga, Tennessee, a garage worker who was inspired after he needed blocks, ropes, and six men to pull a car ou ...

Heart Attack
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often it occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat or feeling tired. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, lack of e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chrysler Building
The Chrysler Building is an Art Deco skyscraper on the East Side of Manhattan in New York City, at the intersection of 42nd Street and Lexington Avenue in Midtown Manhattan. At , it is the tallest brick building in the world with a steel framework, and it was the world's tallest building for 11 months after its completion in 1930. , the Chrysler is the 11th-tallest building in the city, tied with The New York Times Building. Originally a project of real estate developer and former New York State Senator William H. Reynolds, the building was constructed by Walter Chrysler, the head of the Chrysler Corporation. The construction of the Chrysler Building, an early skyscraper, was characterized by a competition with 40 Wall Street and the Empire State Building to become the world's tallest building.

Steam
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

Rush Hour
A rush hour (American English, British English) or peak hour (Australian English) is a part of the day during which traffic congestion on roads and crowding on public transport is at its highest. Normally, this happens twice every weekday: once in the morning and once in the afternoon or evening, the times during which the most people commute. The term is often used for a period of peak congestion that may last for more than one hour. The term is very broad, but often refers specifically to private automobile transportation traffic, even when there is a large volume of cars on a road but not many people, or if the volume is normal but there is some disruption of speed. By analogy to vehicular traffic, the term Internet rush hour has been used to describe periods of peak data network usage, resulting in delays and slower delivery of data packets. Definition The name is sometimes a misnomer, as the peak period often lasts more than one hour and the "rush" refers to the volume ...
