I learned how to perform the analysis for this pipe network system and managed to calculate the flow rate in this system. Besides, I have a deeper understanding in the major and minor losses. I can also define the pipe network system of a specified configuration in a building to be designed. I can also determined the required pump power to feed the water to the elevated reservoir in the given water feeding system.

For my research paper this fall I will be talking about Senator Jon Tester's voting habits on the Keystone XL Pipeline. The Keystone XL Pipeline was a bill passed by the Senate by a vote of 62 to 36. This bill would allow the oil to be ship from Alberta to Illinois and then to Texas to be refined and sold. Jon Tester was one of the sixty-two members who supported the Keystone Pipeline because of its benefit on Montana's jobs and economy. However, Jon Tester has also spoken about how Montana and the United States needs to work towards cleaner energy alternatives.
In the piece “Stainless steel all along the soda fountain”, Wah uses soda fountain as a symbolism to express the joyfulness and struggle of his hyphen identity. Wah’s father instructed him to keep the soda fountain clean, taught him to utilize the equipment, and finally Wah surpasses his father by making the soda fountain the “smoothest, shiniest, snazziest soda fountain in town” (41) and creating his own special. Wah comes to his own identity that he emphasises his struggles of adhering to western modernity, and expresses his calm facade and his rebelliousness inside him.
Rachele Liba Professor Whitehead POSC 100 22 July 2016 Placing a Price on a Green Nation Having lived a nomadic lifestyle across the United States, I have had the opportunity to witness the wonders of our flourishing society and the everyday turmoils that we face. Rigorous innovation has helped Americans fulfill countless dreams, however with every gift there is a usually a price-tag or opportunity cost. Now in the midst of the general presidential election, platforms that represent our beliefs can undergo much needed reform to address the opportunity costs that were surpassed in the process of success. Among the various problems found in our society, a key movement that has raised necessary controversy has to do with environmental policy.

The keystone pipeline has created great debate among the government of the United States and Native American’s living close to where it would be. There have been several attempts by the counter parts to convince the general public what to do. An example of these are the “Reject and Protect” Cowboy and Indian Alliance Anti-Pipeline Ad and the Support Keystone Pro-Pipeline Ad. The Anti-pipeline add starts with images of the Native American’s and Cowboys together. In the background we can hear Native American chants witch could be used to be more sympathetic with the subject.
As you must know, the Dakota Pipeline has been a residing issue for a while now. I believe that we should continue the production of this pipeline. Building this pipeline will benefit our country in multiple ways. For example, by building the Dakota Pipeline, 8,000 to 12,000 jobs will be created.
Throughout the centuries, humans have been attempting to find a way to power homes, cars, and other luxuries in the most efficient way possible. Coal and oil were two major sources that begin being exploited during the industrial revolution. Both have caused great controversy over the years from lawsuits to strikes. A new way to drill oil, hydraulic fracturing, was discovered and was an efficient means of drilling until its effects became prevalent. Also, when coal began to run out, a new method called mountaintop removal took hold, but continues to damage the earth.
I think a huge problem in our society is all this talk about the North Dakota Pipeline. In my honest opinion i think it is wrong. There is many people who use the water supply and if something happens with the pipeline it could contaminate the Native Americans water supply. There is many people who count on the water and use it everyday for cooking, cleaning, and drinking. If they go through with the pipeline act it could kill many Native Americans because we need water to survive.
Attorney General, I am writing on the behalf of the Sioux Nation's stand against the pipeline that threatens their land, water, health, and future. Although their stand is a way to advocate for their rights laid out int the Universal Declaration of the Rights of Man (1948) and should be supported, the primary reason I write are as follows: 1)Pipeline action violate the 1868 treaty that the U.S. has made with the Sioux Nation 2) Militarized tactics (rubber bullets, etc.) used against the nation's people for standing for looking after their health and the ecology of the land is attrocious. 3) There is a comonent of the above said actions that seem to violate the Sioux peoples' Freedom of Religion. I am extremely concerned
In recent years in can be noted that civil disobedience is prominent in American culture. This can be portrayed in the recent events of the Keystone Pipeline activists. Many activists have blamed the government for their problems just as Thoreau did in his essay “Civil Disobedience”. There can be a parallel drawn between these two topics even though they have decades between them. In these times it is still logical to believe that civil disobedience is the right course of action.
As an aspiring engineer this topic is very important to me because I may work in this field when I am older.
Natural Resources minister is under fire from Liberal minister for harmful comments about the approval of the Kinder Morgan pipeline. He apologized for the comments he made about pipeline protests that some people mis-interpret his speech as a threat of their communities. Carr made comments about the possible use of defence forces during future protests to put their safety over pipeline projects approved by Ottawa. The controversy was started when Carr told the crowd "If people choose for their own reasons not to be peaceful, then the government of Canada, through its defence forces, through its police forces, will ensure that people will be kept safe"(Lazzarino). Some First Nations made a promised to protest over the Liberal government controversial
Canadian company TransCanada hopes to build Keystone XL a pipeline that carries Canadian tar sand oil from Canadian border to the Golf Coast. According to Derber “the pipeline extracts some of the dirtiest oil on the planet, a process that sends many polluting chemicals into the ground waters and releases methane, the most potent greenhouse gas, into the air, creating one of the greatest climate threat” (p. 115). A leak from a pipeline carrying the tar sand oil could cause environmental damage and pollute our drinking water and agricultural irrigation. The builders of the Keystone XL Pipeline are wilders. According to Derber, “environmental wilding in the natural environment, such as reckless polluting that causes global warming” (p. 11).

Von Mises [3] states that “the forces due to viscosity appear as products of μ and expressions that have the dimensions area times (velocity / length)”. By further investigation, the mathematical analysis of these principles leads to a system of partial derivatives known as the Navier-Stokes equations. These equations are used to describe fluid flow and can be used to solve specific dynamic fluid flow cases. These include; velocities, pressure, temperature, density and can also be used to solve viscous problems of a dynamic fluid flow problems. These partial derivative equations relating to the specific variables are extremely complex and time-consuming to
