“Is the steel pipe indicated in Section 10.1.3 allowed to be Schedule 10 galvanized?” We have reviewed NFPA 24, 2010 edition that you indicated as the applicable standard as well as the 2016 edition. Our informal interpretation is that Schedule 10 galvanized pipe can be used. Section 10.1.3 refers to steel pipe that is externally coated and wrapped and internally galvanized between the check valve and the outside hose coupling for the fire department connection. There is no indication of the minimum pipe thickness. The commentary from the 2010 edition of the Sprinkler Systems Handbook indicates that steel pipe can be used for piping to a fire department connection because the fire department connection is an auxiliary water supply for

As such, the check valve or backflow assemblies will require the internal inspection. The CPVC pipe will not require an internal inspection per 14.2.1.5. This says that nonmetallic pipe shall not be required to comply with Section 14.2 that addresses the assessment of internal condition of piping. This addresses the question regarding apartments and hotels. Residential dwellings with NFPA 13D systems are not within the scope of NFPA 25 per 1.1.5. There is an exception in 16.2 for small residential board and care occupancies with NFPA 13D systems. Paragraph 16.2.1 says that the requirements in this section shall only apply to residential board and care facilities with sprinkler systems installed in accordance with NFPA 13D as described in NFPA 101, Life Safety Code. Paragraph 16.2.1.1 says that systems installed in accordance with NFPA 13D, shall be inspected, tested, and maintained in accordance with 33.2.3.5.8.1 through 33.2.3.5.8.15 of NFPA 101, which reference specific sections of NFPA 25. The frequency of the inspection, test, or maintenance shall be in accordance with [NFPA 101], whereas the purpose and procedure shall be from NFPA 25 [101:33.2.3.5.8]. The referenced sections do not mention check valves or backflow prevention assemblies for

A presumption we used was a diameter for each of the parallel pipelines, amongst pipeline AB, pipeline BC, and pipeline CD. We settled for a diameter of 0.3 m for all circumstances and executed the energy equation between the respective locations, to confirm whether the calculated discharge was agreeable. The discharge was acceptable in each of the three circumstances. In the event that it was unacceptable, another diameter was required to be chosen and the energy equation would need to be recalculated.
The Atlantic Coast Pipeline is a proposed natural gas pipeline that is planned to go through three states along the east coast; West Virginia, Virginia, and North Carolina. The pipeline is claimed to create 19,440 jobs and provide clean reliable power to the residents within the borders of the three states. The pipeline seems to be beneficial in improving the livelihood of the residents of these states, however, the pipeline is also taking from the communities it is planned to go through. The Atlantic Coast Pipeline has created some controversy, among individuals especially when it comes to the equity of specific communities. Equity is the quality of being fair when it comes to making decisions.

Although some might agree with the construction of the $3.8bn oil pipeline that would cross four states, others are opposed to that construction strongly, and things got violent recently. Protests are made to get a point across but that does not mean things won't get violent. For instance, there is a big protest that is taking place in North Dakota, that involves the construction of the $3.8bn oil pipeline being constructed on sacred land. Protesters are opposed to this construction since this pipeline would transport oil crossing the Missouri River less than a mile away from the Standing Rock Reservation. Not long after construction crews began doing their work, the protest started to get violent. In the article, “North Dakota Pipeline Protest
The Interest Group Agendas section in Chapter 5 interconnects that diversity of legislators’ views reflect, or certainly parallels, that of group interests (Rosenthal, A., 2004). This type of correlation points out the important factor that helps groups to surpass individuals on decision-making responsibilities and the mode of interdependence they have. However, positively interdependent (supportive) groups tend to make better decisions than both negatively interdependent (economical) groups and individuals, particularly in complex tasks (Johnson & Johnson, 2012). The Keystone Pipeline System is known as the oil pipeline system in Canada and the United States contracted in 2010 and is presently owned exclusively by TransCanada Corporation. The once-obscure Keystone project became a political symbol amid broader clashes over energy,
Where would we be without electricity today? Electricity has changed the world as we know it and is always advancing. Have you ever thought about who helps keep it under control or who installs the wires capable of moving electricity from room to room in your house? Most likely you have never wondered, until the moment it goes out or has problems. This is where one would find out that an electrician can help with these problems.
Many Americans seem to be anxious about how the world perceives them, and are disturbed by what seems to be its declining image and position in many countries. Some wonder if the end is near for U.S. dominance or influence. The following are some quotations from recently published materials that are worth considering.
Imagine living in a third world country with overcrowded houses and no job. That is how, “about 22% of our country’s 5.2 million Native Americans live” (A Program of Partnership With Native Americans). Right now Native American people take up about 2% of all land in North America, most of it being around the area of North and South Dakota. Over the past week there have been protests over the insertion of an oil pipeline through the Native American people, mainly the Standing Rock tribe’s, sacred land. This new pipeline would, “threaten water supplies for the Standing Rock Sioux and millions of others downstream, and its route would destroy tribal burial grounds and sacred cultural land” (Healy). Many of the Native American people, along
A topic I explored was burst street pipelines. At the beginning I realized the issue because it was constantly being brought up in the news on how busted pipelines were leaking thousands to millions of gallons of water. Consequently it made me angry especially with the ongoing drought in 2015 and 2016 and I was curious as to why these things were not being addressed earlier before they happened. I researched and found out that to replace all the old infrastructure throughout the United States would be in the billion dollar range. I also researched how little freshwater is becoming available and how the leaking water will sit in the ground for a hundred year till it is recycled back. With this information I was intrigued to come up with a solution
ST pipelines originated in the USA where they were first used in 1896 in the form of corrugated steel pipe culverts. Since then, steel pipelines for water supply have been used extensively throughout the world, including the UK. One of the earliest steel water pipe installations in the United States, still in service today, was in San Francisco in 1863.
