While designing any aerodynamic body an unspoken assumption of bilateral or mirror symmetry is taken into consideration. Argument against this bilateral symmetry states that “once the velocity of sound is exceeded, the laws of aerodynamics change in such a way as to make it seem inadvisable to arrange the components of an airplane side by side or abreast in a supersonic stream unless there are compelling reasons for such an arrangement.“ 2.1.1 Wave Drag This type of drag is formed as a result…

ABSTRACT Flakiness & Elongation index is one of the most prominent criteria that govern behavior and performance of aggregate in the bituminous mixes. The strength and serviceability requirements of bituminous mixture such as Stability, Flow, Voids in Total mix (VTM), Voids Filled with Bitumen and (VFB) highly depend on the physical properties of aggregates. This study conducted by observing the effect of flakiness & elongated index by adding different percentages from 0% to 50% of flaky &…

Problem: how does the angle of trajectory effect the horizontal distance of a bottle rocket Background research: When an object is in the air and has no forces acting on it other than gravity it becomes a projectile. (Henderson, 1996) Gravity causes the projectile to accelerate toward the ground in a uniform arc like a rainbow does. this shape is known by scientists and mathematicians as a parabola, and objects that fly in the shape of a parabola are said to be in parabolic motion. A projectiles…

Everybody has heard of paper maché, but not everyone knows of the much more useful alternative, paper maché clay. It’s simple to use, and easy to fill a space. It is much better than normal paper maché clay, even if it has it’s flaws. The benefits far outweigh the flaws, making it an extremely useful tool in making masks. Masks can be made from all kinds of material, but using paper maché clay is the easiest way to have the most artistic freedom. Paper maché clay can be messy, but so can paper…

2, through the ½” nominal diameter, type L copper pipe, through the needle valve WV5 (Appendix A), and back to Tank 2. WV5 was initially closed. The Honeywell STD 924 DP meter’s pressure tap lines were placed at PT 1, just before the P-1 Sterlings Fluid System Peerless Pump PE50B1, and PT 10, just after WV5. A Fluke 179 multimeter was attached to the DP electrical box. The multimeter was set to read electrical signal in the form of DC current with units of mA. A Fisher Scientific thermocouple…

location. In land this called declination error. * Deviation * Caused by localized magnetic fields in the aircraft. * Dip Errors COMPASS SWINGING – a maintenance procedure that corrects a magnetic compass for deviation error. COMPASS FLUID – similar to kerosene and used to dump the oscillation of the compass card. COMPASS ROSE – a location on an airport where an aircraft can be taken to have its compasses “swung”. Lines are painted on the rose to mark the magnetic in 30 degrees…

Application of Bernoulli’s Equation to Fluid Dynamics Bernoulli’s equation has been used widely in an engineering aspects, the conservation of energy is the most famous one. This paper will talk about the application of Bernoulli’s equation to fluid dynamics. Fluids flow can be in different forms, such as water in the ocean, blood within our body and etc. Thus, it is necessary to study the mechanism of fluids. In the year of 1738, Daniel Bernoulli published a book called Hydrodynamica, which…

Members from BHP Billiton LTD, have approached filtration consulting, to design a cyclone separator system for a process involved in the production of zinc oxide particles. The clients has also asked for advice on the use of bag filters as a standalone system, or in conjunction with a cyclone separator system. The filtration system must have a collection efficiency of 95% of the zinc oxide particle from a gas flow at 1000°C and with a flow rate of 3820 (Nm^3)/hr. One of the most common particle…

Where P is the permeability coefficient, Q is the amount of permeant passing through the material, x is the thickness of the plastic film, A is the surface area available for mass transfer, t is the time, and ∆p is the change in permeant partial pressure across the film. Hence the permeability coefficient (P) is the proportionality constant between the flow of the penetrant gas per unit film area per unit time and the driving force (partial pressure difference) per unit film thickness. The…
