BOUNDARY LAYER THEORY INTRODUCTION The concept of boundary layer was 1st introduced by L.Prandtl in 1904. Figure 7-1. Viscous flow around airfoil A structure having a shape that provides lift‚ propulsion‚ stability‚ or directional control in a flying object. Boundary layer is formed whenever there is a relative motion between the boundary and the fluid. Boundary layer thickness: 1. Standard thickness - signified by ‚” it is define as the distance from the boundary layer

To have the designation of scholar is an academic honor that requires more than just having excellent grades it requires collaboration with those who have earned the title‚ participation in massive research projects‚ and the experience of portraying wisdom. We most often think of scholars as an elderly person who has years of devotion to a study. We take for granted their knowledge comes over time that teaches us more than the days will ever know. It takes extreme dedication to be a scholar. A

Crust is the first and upper most layer of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This layer is made frequently from granite rocks and is solid. Continental Crust is approximately 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This part of the Crust is made from basalt rocks. The Crust is most of lithosphere and is the coolest layer by far. Mantle is like silly putty consistency. It is the largest layer of Earth sitting under the Crust.

Routers are specialized devices that links and routes everyone ’s information over networks and the Internet through thousands of pathways. The main processes of the router include locating a pathway to create a link to and transmitting packets through this path. This process is done by routing data from a computer to a LAN through any number of routers to reach its destination. The router has proven itself to be one of the main components in the success of the Internet. Routers make networking possible

Brooklyn Bridge by Joseph Stella and the photo Brooklyn Bridge by Walker Evans a comparison of the two artistic figures‚ colors utilized‚ perception‚ painting verses film‚ and the mood each creates reveals that the oil on canvas that Joseph Stella is the more interesting presentation of the Brooklyn Bridge. The two artists portray the same subject in two totally different ways that change the mind and artistic finding of their audiences. The painting and the film depict the same bridge with different

Difference between OSI model and TCP/IP model The Internet Protocol Suite also known as TCP/IP is the set of communications protocols used for the Internet and other similar networks. It is named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP)‚ which were the first two networking protocols defined in this standard. IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s‚ namely

The ozone layer is a layer in Earth’s atmosphere which absorbs most of the Sun’s UV radiation. It contains relatively high concentrations of ozone (O3)‚ although it is still very small with regard to ordinary oxygen‚ and is less than ten parts per million‚ the average ozone concentration in Earth’s atmosphere being only about 0.6 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above Earth‚ though the

rocky mantle‚ which is composed of silicon‚ oxygen‚ magnesium‚ iron‚ aluminum‚ and calcium. The upper mantle is rigid and is part of the lithosphere (together with the crust). The lower mantle runs slowly‚ at a rate of a few centimeters per year. 3. Core: The Earth has an iron-nickel core that is about 2‚100 miles in radius. At the core-mantle boundary‚ composition changes. Seismic waves suggest this material is of a very high density (10-13 g/cm3)‚ which can only correspond to a configuration
