Essay On Hydraulic System
Introduction of Hydraulics One of the most substantial systems used around the world when dealing with machinery is hydraulic systems. Hydraulic systems are used in a wide variety of applications from small types of machinery to massive complex assemblies. The word “Hydraulics” can be simply defined as the usage of a compressed or confined liquid to produce power, motion, or force. It is derived from the greek words “hydro” which means water, and “autos” which means pipe. “The basic idea behind any hydraulic system is very simple: Force that is applied at one point is transmitted to another point using an incompressible fluid. The fluid is almost always an oil of some sort. The force is almost always multiplied in the process.” (How …show more content…
When dealing with fluid flow and fluid systems, it’s important to understand what kind of viscosity the fluid has to better control the output of the system. A big factor that affects viscosity is the temperature in which the fluid will be in. If the fluid is in a higher temperature, the viscosity will be low and the flow will be high. If the fluid is in a lower temperature environment, the viscosity will be higher and the flow will be lower. Making sure that the user has the proper viscosity and flow is key in having the maximum performance for the system. When it comes to temperature, the fluid must be required to be somewhat fire resistant and have a good “Pour point.” When dealing with the fire resistance, the chosen fluid must not allow a flame to flash back to the source of ignition and should not sustain a combustion after the source of ignition is removed. If the fluid does, it can cause serious issues and/or damage the equipment or users of the hydraulic system. On the contrary, the fluid must also have an adequate pour point. The pour point is the coldest temperature the fluid is able to flow without freezing. When choosing the fluid for an hydraulic system, the rule of thumb is to choose a fluid that can withstand 20 degrees lower than any expected temperature to allow a type of safety net for the

Pros And Cons Of Hydraulic Fracturing
1217 Words | 5 PagesA lot of water is actually needed to in the hydraulic fracturing process. About 200 tanker trucks worth of water to be exact. The mixture is pumped at a high pressure at furthers 10,000 feet into the ground. This causes the rock to crack. Fissures are opened and kept open by the sand from the mixture.

Hydrofracking Research Paper
1593 Words | 7 PagesThroughout 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.
Pros And Cons Of Fracking

The Pros And Cons Of Oil Fracking
1686 Words | 7 PagesIt is one of the many ways people have used to get oil by drilling into the ground. Hydrofracking is a combination of horizontal drilling and hydraulic fracturing. The goal is to drill about a mile, sometimes more, into the Earth to get to the Marcellus formation,
Lab Report Determining Unknowns Through Distillation
767 Words | 4 PagesDetermining Unknowns Through Distillation Introduction Distillation is a technique of separating two miscible liquids by their boiling point differences. This experiment uses distillation to separate and identify two unknown compounds. The two types of distillation are simple and fractional. Simple distillation is used to separate miscible liquids that have a boiling point difference of 100 C or more, while fractional distillation is used to separate miscible liquids that have a boiling point difference of less than 100 C. Simple distillation and fractional distillation have two similar but different apparatuses. The fractional apparatus is set up the same as a simple apparatus, but a column packed with steel wool is added in between the boiling

Starting with sodium chloride, this is a compound that has the following physical properties: colourless, transparent, crystal structure, salty taste, boiling point of 1465 degrees Celsius, melting point of 8000.7 degrees Celsius, and is soluble in water (Sodium Chloride, PubChem). Silicon dioxide, which is also known as silica, has the physical properties of odourless, a boiling point of 2230 degrees Celsius, a melting point of 1710 degrees Celsius, and is insoluble in water (Silicon Dioxide, PubChem). Furthermore, octane is an alkane that that has the physical properties of colourless, clear, liquid, a boiling point of 125.6 degrees Celsius, a melting point of -56.73 degrees Celsius, and is soluble in water (Octane, PubChem). When connecting back to the Athabasca Oil Sands, on average, the sediments and oil are mixed together with

Essay On Diesel Truck
619 Words | 3 PagesThere has always been those certain environmental people that say that diesel trucks are bad for the environment. What those people do not usually know is not surprising to anyone that knows a diesel engine. The only thing that they know to say is "that black stuff that comes out of the truck when they "roll coal" is bad for the environment. A diesel has many different ways that make it a better vehicle.
Bernoulli's Theorem Essay
734 Words | 3 PagesVon 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
Competitive Case Analysis Of Wilkerson's Company
1770 Words | 8 PagesNonetheless, competitors of Wilkerson overlooked the opportunity to make profit for themselves in flow controllers, due to the fact that Wilkerson has increased the product price by 10% without losing any business. President of the Wilkerson Company was discussing the business’s operating results with his financial controller and manufacturing manager. Reason for this meeting was because; competitors were now reducing the price of their pumps, posing a threat to Wilkerson’s major product line. Since pumps where a commodity product for Wilkerson, they had no other choice but to match the competitors price in order to maintain volume. Unfortunately, Wilkerson’s price cuts led to a decline in their company profits, especially in the pump line.
