The blast wave generating device developed for this project consists of two sections that are equivalent in cross sectional area to the expansion section channel of the shock tube; the front section has internal damper blades that rotate from a vertical position to a horizontal position, and the rear section is equipped with internal flow straighteners. The device is to be placed in series between the expansion section and the expansion section channel, and bolted together with the flanges of…

Shell drilling camp notes Day 1- we learned health, safety and emergency procedures when off shore. Such as how to get out of a sinking helicopter, how to properly swim once floating in the water, team techniques to increase our chance of survival, and use lifesaving equipment if need to abandon ship/platform. Then we learned why it is important to follow safety regulations and why certain procedures are done and how it is everyone's responsibility to prevent it. As well as how the Piper drill…

The bouncy ball is way bouncy then the tennis ball, because the bouncy ball is made of the rubber and when it hits the ground it gets compressed, or squished and because it is very elastic, it returns to its original shape very quickly. That's the only reason why the bouncy ball is way bouncier than the tennis ball. Bouncy ball was made by the one and only norman stingley who worked at the california chemist. He used to just experiment stuff with rubber on his spare time. By doing all the…

The first and foremost procedure for this lab is to be familiarized with the lab equipment. The principle components to be interacted in this lab is the work station, the wind tunnel, the AOA adjusting handle, the airfoil with tufts, and the wind tunnel frequency controller. Switch the control mode for the tunnel frequency controller to be LOC or local of local control would be used instead of remote control. Make sure that the tubes are connected in a way such that the air and pressure should…

Introduction Bernoulli principle is a statement of conservation of energy per unit mass for an ideal fluid in steady motion, where it states the sum of pressure, kinetic and potential energies per unit volume is constant (Munson, et al., 2013). Venturi effect is where the pressure of the fluid decreases which causes its velocity to increase as it passes through a constricted section of a pipe. This is the basis of this report’s investigation. The aim of this investigation is to compare the flow…

Therefore, if the pressure filter is semi blocked (not fully blocked), the flow rate decrease at the orifice makes the pressure at pump will be increased and suddenly, the pressure decreases after pass the orifice. Schaschke (2005) stated that a drop in fluid pressure because the increase in the cross-section causes a reduction in velocity and an increase in pressure. The kinetic energy is decreased and the potential energy which is in a form of pressure will increase simultaneously then, they…

Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is…

production rate and helps understanding how the flow rate is affected by different parameters (Lund). Additionally, in order for fluid to flow there has to be a pressure gradient. As this pressure gradient increases the fluid flow rate increases as well. The Darcy equation incorporates pressure gradient by a negative sign in the equation. The negative sign indicates that fluid in a high pressure area will flow to an area of low pressure. Pressures are related to extracting hydrocarbon from a…

which come across the wind are classified as bluff bodies and stream-lined bodies. Bluff bodies are the ones with sharp edges and regular geometrical features. Stream-lined bodies are the ones which have a definite stream-line shape. Wind being a fluid, behaves differently when it strikes either type of bodies. As the wind strikes the stream-line bodies, it glides across the surface, and follows a laminar…
