Prac Report – Investigating Parachutes Experiment Aim: To measure how the size of a parachute t’s surface area affects the parachute’s speed‚ acceleration and time of flight. Hypothesis: A parachute with a larger surface area would fall slower due to that fact there would be a higher level of drag‚ or in other words more air resistance. Materials: * Sturdy garbage bags * Metric ruler * Scissors * Washers * Twist ties * Light-weight string * Stopwatch Method:

The current report serves the purpose of analyzing strengths and weaknesses of existing DOS-based POS terminals used by Zara and providing recommendations as to whether an upgrade is necessary. Methods of analysis include decision tree and SWOT-matrix‚ cost analysis‚ risk assessment‚ along with expert opinions summary from IT-consultants in retail industry. Even though the old POS terminals are easy to install and stable to operate‚ they impose limitations on data interchange capabilities‚

September 2007 Terminal velocities were measured for both tef (Eragrostis tef (Zucc.) Trotter) grains and straws using the suspension velocity method. The terminal velocity of tef grains increased linearly from 3.08 to 3.96 m sÀ1 with increase in moisture content from 6.5% to 30.1% wet basis (w.b.). Straws with different lengths‚ node-free‚ with a node in the middle‚ and with a node at the end were tested for their terminal velocities. Straws with nodes had higher terminal velocities compared with

paper is to review the literature on the principles governing gravitydriven separation of liquid-vapor mixtures‚ review design methods for separators‚ and develop a model that predicts separator performance given operating requirements (i.e. size or velocity‚ and design droplet size) subject to design constraints. The model presented can serve as a basis to establish a fundamentals-based new design method for gravity separators. It is not the purpose of this paper to develop or recommend design guidelines;

reaches its so-called terminal velocity. Different objects have different terminal velocities. The terminal velocity of a human being falling through the earth’s atmosphere -- a skydiver with an unopened chute‚ for instance -- is about 120 mph (193.1 kilometers per hour). That’s surprisingly slow‚ but still fast enough that a person falling from an airplane would make a pretty big splat upon hitting the ground. The idea of a parachute is to reduce a person’s terminal velocity and make a long

London Heathrow Airport Project Introduction The London Heathrow Terminal 5 (T5) project was one of the most complex projects ever undertaken in the United Kingdom and was the biggest construction site in Europe. The total investment in the T5 project was £4.3 billion and took approximately 37 million person-hours to complete. Elements of the Terminal 5 project include the main terminal‚ two satellite terminals‚ air-traffic control tower‚ and connections to public transport‚ road works‚ rails

Abstract— The calculation of dispersion curves and‚ therefore‚ the rheological properties is possible by analyzing how the different phase velocity modes behave in the medium of interest. Shear wave propagation in “thin” organs is affected by the mechanical properties of the tissues surrounding those organs. In order to obtain the proper mechanical properties of such boundary sensitive organs‚ an analytical solution for the dispersion curves on a plate surrounded by semi-infinite solids was derived
