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

Layers of the Atmosphere The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified using... • thermal characteristics (temperature changes)‚ • chemical composition‚ • movement‚ and • density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics‚ chemical composition‚ movement‚ and density occur. Troposphere The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20

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.

Performed: July 10‚ 2013 Group No.: 4 Date Submitted: July 17‚ 2013 Experiment #1: Measurements INTRODUCTION Density is a physical property of matter‚ as each element and compound has a unique density associated with it. The unit of Density is g/cm3 or g/mL. It is used to measure thr relative “heaviness” of objects with a constant volume. As defined‚ the formula for Density is Mass over Volume (ρ=m/v) and it can be rearranged to get the Volume (v=m/ρ) or Mass (m=ρv) of a certain substance

EXECUTIVE SUMMARY: The main objective of this project was to carry out a design on the Propane distillation column for a process that produces 1‚3 Butadiene. The raw materials used are Butane‚ Oxygen and Water and the process capacity is 100 000 tonnes per annum nominal. In the previous work it was stated that the plant is located in China. The main location of the plant is in the capital city of the Gansu Provence‚ Lanzhou. This was decided as the location over other provinces due to the excellent
