“We have a metal building with a gas furnace located above a lay-in ceiling. The local AHJ is telling us that we are required to have sprinklers above the ceiling since there is a gas furnace above the ceiling. Are sprinklers required?” In response to your question we have reviewed NFPA 13, 2010 edition that you indicated as the applicable standard. Our informal interpretation is that sprinklers are not required. The commentary in the 2010 edition of NFPA 13 Handbook under Section 8.15.1.3…
the car will be made, but it will serve as a decent sample. The car itself will depend on three main power sources: solar power, wind power, and kinetic energy recovery, or more commonly known as regenerative braking. The solar panels will cover the top of the car, which is about 105.214 feet squared, or about 9.775 meters squared (Model S). However, the windows cannot have solar panels on them as they would make it impossible for the driver to see out of them. With an estimation, this would…
Neon is one of the world’s rare and most expensive elements. I chose Neon because of it's uniqueness. In 1898, William Ramsay and Morris Travers at University College London isolated krypton gas by evaporating liquid argon. They had been expecting to find a lighter gas which would fit a niche above argon in the periodic table of the elements. They then repeated their experiment, that time allowing solid argon to evaporate at a slow pace under reduced pressure and collected the gas which came off…
Mercury, Venus, Earth, and Mars are known as the terrestrial planets. In comparison to the outer planets, they are small in size, made of denser materials, and lack a huge numbers of moons. Even though they share these common traits, they are still very different from each other. Mercury is the closest planet to the sun, yet its surface is either extremely hot or extremely cold due to the slow rotation of the planet on it's axis and the lack of atmosphere. It is also unique in that it's core is…
different technology forms. One is wind power. They whole use turbines to catch the wind and transfer it to power. Another way is solar. They would use solar power panels to turn sun rays into power. There are actually two different types of solar panels. One is called a solar PV that just goes on the roof or a yard to generate enough power for the house. Another is called a CSP solar panel. This panel stretches across a plain and gives enough power for almost all of Australia. The third one is…
Mars harboured long-lasting lakes and water streams about 3.8 to 3.3 billion years ago, boosting the odds that life may have once existed on the Red Planet, scientists, including one of Indian-origin, have found. Using data from the Curiosity rover, NASA's Mars Science Laboratory/Curiosity team has determined that, long ago, water helped deposit sediment into Gale Crater, where the rover landed more than three years ago. The sediment deposited as layers that formed the foundation for Mount…

Scientists and astronomers are always trying to find out more and more about the outside world. The rings of Saturn are one phenomenon that astronomers are continuing to study. Just recently, it was revealed that these scientists who were studying these rings came to a few surprising theories. THEORY NUMBER 1 ON THE SATURN RINGS It has been concluded by astronomers that the more opacity that something has doesn't mean that it has more mass. They came to this conclusion while studying the rings…
THE MARINER PROGRAM Mariner 4 flew by Mars in July 1965 This was followed by Mariner 6 and 7 in 1969.The images sent back showed what appeared to be a geologically dead world. There was an abundance of craters much like the moon. It was also from these spacecraft that we learned that Mars' polar caps were made of Carbon Dioxide ice instead of water ice. In 1971, Mariner 9 flew by Mars and mapped the entire planet down to 1 km. These images brought a wealth of information and it soon become clear…
In the past 15 years, astronomers have achieved leaps and bounds in terms of spotting exoplanets. It had gone from producing no results to being possible. One method, known as Transit, involves continually observing stars and noting whenever spots of it become dimmer. By calculating how much of the star’s light was dimmed, astronomers can also indicate the approximate size of the planet’s radius. It can also tell astronomers what the atmosphere of an exoplanet consists of by looking at the light…
