The Effect Of Velocity On A Flat Plate Boundary Layer

A. How did the experiment in Part I demonstrate surface tension? Use your experiment observations when answering this question.

1. What two parameters are responsible for creating the movement (filtration and reabsorption) of fluid across the capillary wall?

The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases from subsonic to transonic.

In this experiment in a low speed flow the static pressure around an aerofoil will be observed and discussed. The lift on the aerofoil will also be calculated and compared with the theoretical value. The aerofoil being used in this particular experiment is symmetrical and is taking place in a wind tunnel with a speed of 18.5m/s, therefore the flow is assumed to be incompressible. The different pressures along the surface of the aerofoil will be measured at an angle of attack of 4.1 degrees and 6.2

Convergent Boundary- At convergent boundaries, two plates move toward one another, colliding and pushing into each other. The plate that is made of oceanic crust can slide down beneath another plate, which forms a deep narrow trench. As one is pushed under the other, the plate begins to melt, which causes a line of volcanoes to form that are in a parallel line to the trench. If both tectonic plates are continental crust, the plates will collapse or break up as they collide, which forms a high mountain

There are three types of place boundaries, convergent, divergent and transform. Convergent boundaries are regions that develop when two tectonic plates collide. The area surrounding the collision becomes mountainous as the plates buckle. This happens through a process called subduction. Divergent boundaries

My boundary is subduction and it is a form of a convergent boundary. An oceanic/continental subduction zone is where two plates (one oceanic and the other one continental) collided. The more dense oceanic plate made of basalt goes under the less dense continental plate made of granite. Where the ocean plate went under it forms a deep sea trench because there is a spot left where the two plates collided and one went under.Volcanic mountains form when stress and pressure builds up and when the lithosphere can’t hold it anymore it flows in to mountains

Convergent plate boundaries is when two plates collide and the more dense plate slides under the less dense. Divergent plate boundaries are when two plates move apart and magma comes up from the earth. Transform boundaries are when two plates slide past each other. At the convergent plate boundaries create either trenches, reverse faults, mountains, volcanos, or island arches are created. The divergent plate boundaries create rift valleys, or mid-ocean ridges. The transform boundaries form normal faults, strike-slip faults, and reverse faults. A form of weathering is at a meander, where the the two sides of the meander are being weathered away and coming closer to each other. This will eventually create an oxbow lake. Erosion is showed, at a glacier since the glacier is eroding away sediments and moving them to different places. Deposition is showed at the bottom of a mountain where rocks have fallen off the mountain and were placed there at the bottom of

The first boundary is the divergent boundary. Divergent boundaries occur when two tectonic plates pull away from each other, or move apart. These tectonic plates move because, “the intense heat in Earth’s core causes molten rock in the mantle to move,” (“How Do Plates Move?” Page 1). The molten rock then breaks into the Earth’s surface causing one of the plate boundaries to occur. Divergent boundaries usually occur

Boundary turbulence refers to a failure in rule coordination between co-owners of private information. It can occur in the form of an intentional violation or could be a case of a privacy dilemma where the privacy of a certain piece of knowledge is unspecified and misconstrued. Boundary turbulence can lead to mistrust however can also lead to improved rule definition between co-owners of personal information. The study draws on the appraisal theories of emotion to look at how people’s perceptions of situations influence their experience and elicitation of emotions. According to this theory, the authors draw upon three negative emotions that boundary turbulence may elicit: hurt, anger and fear. I found this to be an interesting topic of high

This paper’s theme is to illustrate the boundary conditions for a case study. The setup of the study provides for a comparison of Nixon administration leadership and current global private industry leadership to discover if similarities exist. Additionally, the study will examine if private-industry leadership would improve governmental leadership or if the opposite is the case. Because the Nixon administration contained judicial judgments for many of the staffers, these will not be examined in the study.

The first part of this experiment involved calculating the wave speed of traveling waves on a string that was bounded on both sides (i.e. one side bounded by a clamp, and the other by a pulley) for three different tensions being applied. The wave speed was calculated using two different methods:

The concept of boundary-layers was first thought of in the early 1900s by Ludwig Prandtl. He presented a paper in Germany in 1904 which outlined a slightly viscous fluid near a solid boundary cite{Prandtl}. In this paper certain assumptions were made. Firstly the Reynolds number is large, so the viscous terms can be neglected far away from the solid boundary. Then there exists a thin layer of fluid near the solid boundary and this fluid is known as a boundary-layer. Outside this viscous fluid is an inviscid fluid region, which gives rises to a multideck structure. This boundary-layer has a thickness of $delta$ and is proportional to Reynolds number by $delta/L propto {Re}^{-1/2}$, where $L$ is the characteristic length scale of the solid boundary. The pressure from outside the boundary-layer is not significantly different from the pressure inside the boundary-layer. The boundary condition for pressure can be approximated by the value of upper boundary in the inviscid region. Rescaling the wall normal coordinate $y$ by the boundary-layer thickness ${Re}^{-1/2}$ implies that we are located within the boundary-layer and this retains some viscous terms. The following scalings are introduced to perform analysis within a boundary-layer

In a Natural convection flow, buoyancy and density effects are significant for the heat transfer phenomenon. If a hot object is placed in a still air, the layer of air that is in contact with the object is heated and as a result its density decreases. The air surrounding the heated layer of a fluid is cold and of high density. As a result, the less dense air rises upward while the air of high density moves towards a hot object under the buoyancy and density effects. This results in a phenomenon of “Convection currents” that gives rise to a Natural convection phenomenon as shown in the figure 1. The figure 2 demonstrates the case for the cold object placed in a still air results in an opposite phenomenon.
