Why seismic survey method is widely used in oil and gas exploration? Seismic survey is a method used during the exploration phase of oil and gas development. The method gives a first idea of what is present underneath the earth’s surface. The reflected and refracted seismic waves are recorded by a receiver (geophone or hydrophones […]
Has anyone ever died from turbulence?
Has anyone ever died from turbulence? Each year, approximately 58 people in the United States are injured by turbulence while not wearing their seat belts. From 1980 through June 2004, U.S. air carriers had 198 turbulence accidents*, resulting in 266 serious injuries and three fatalities. Can a plane be brought down by turbulence? TLDR – […]
What are three necessary parts of a radio communication system?
What are three necessary parts of a radio communication system? There are three main components to most distributed antenna systems. These components include the Donor Antenna System, the Bi-Directional Amplifier, and the Distributed Antenna System. All three components work together to produce clear in-building communication signals. What is a radio system? A radio “system” is […]
What is the advantage of composite construction?
What is the advantage of composite construction? Advantages of Composite Construction The concrete acts together with the steel to create a stiffer, lighter, less expensive structure. Speed and simplicity of construction- faster to erect, nearly 25% faster then traditional construction. Lighter construction than a traditional concrete building. What has more pop aluminum or composite? In […]
How many workplace fires occur each year?
How many workplace fires occur each year? During the five-year period of 2007-2011, NFPA estimates that U.S. fire departments responded to an average of 3,340 fires in office properties per year. These fires caused an annual average of four civilian deaths, 44 civilian fire injuries, and $112 million in direct property damage. How often do […]
What are 5 chemical properties?
What are 5 chemical properties? Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. What are the chemical and physical properties of metal? Physical properties Metals Non-metals Good conductors of electricity Poor conductors of electricity Good conductors of heat Poor conductors of heat High density Low density Malleable and […]
What are the 2 prime factors of 12?
What safety factor should you perform before enter a curve or sharp turn?
What safety factor should you perform before enter a curve or sharp turn? Centrifugal force results in strong outward pull on your vehicle. So what you need to do before entering a curve is slow down. Lowering your speed when you’re already on a curve may cause your car to skid. Look for signs indicating […]
Why are water towers elevated?
Why are water towers elevated? The primary function of water towers is to pressurize water for distribution. Elevating the water high above the pipes that distribute it throughout the surrounding building or community ensures that hydrostatic pressure, driven by gravity, forces the water down and through the system. Where do cities put their water towers? […]
What variables affect the efficiency of a heat engine?
What variables affect the efficiency of a heat engine? The thermal efficiency of a heat engine is expressed as a product of the Carnot efficiency, the external irreversibility factor and the internal irreversibility factor, by which the three factors that affect the thermal efficiency can be clearly distinguished, and the influences of the external and […]
