Impact Of a Jet Introduction: Over the years‚ engineers have found many ways to utilize the force that can be imparted by a jet of fluid on a surface diverting the flow. For example‚ the pelt on wheel has been used to make flour. Further more‚ the impulse turbine is still used in the first and sometimes in the second stages of steam turbine. Firemen make use of the kinetic energy stored in a jet to deliver water above the level in the nozzle to extinguish fires in high-rise buildings

IMPACT OF A JET OBJECTIVES: To measure the force generated by impact of the jet on vanes of various shapes. To compare the results from the experiment with the theoretical calculations. APPARATUS: The Jet Impact Apparatus Volumetric Hydraulic Bench/Water 3 different shapes of vanes; Flat Plate‚ Conical Cup‚ and Hemispherical Cup Stop Watch 1. INTRODUCTION One way of producing mechanical work from fluid under pressure is to use the pressure to accelerate the fluid to a high velocity

1.0 ABSTRACT The purpose of the impact of jet experiment is to design a system to determine the force generated by the impact of jet on a variety of target vanes. A formula is given to calculate the reaction force at the different vanes caused by the jet. At the end of the experiment‚ the data collected and results calculated will then be compared to theoretical values which are given. Students are expected to be able to come to a conclusion regarding the relationship between the reaction force

A jet engine‚ like a rocket engine‚ is a reaction engine. It works by throwing mass in one direction and taking advantage of the reaction in the opposite direction. In the case of a jet engine‚ the engine burns fuel (like kerosene) with air from the atmosphere. The burning fuel heats and expands the air‚ and this hot air shoots out of the exhaust-end of the engine to create thrust. Most modern jet engines use a turbine to improve the efficiency of the engine and allow the engine to work at low speeds

particular company to standout‚ they must be of high quality. Value adding is a way of differentiating a company from the pack. This paper through qualitative evaluation of JetBlue Airways case study is going to look at some of the reasons as to why value adding is an important marketing strategy. Introduction JetBlue airways‚ as stated by Bodouva & Bodouva (2004)‚ began its operation in February 2000 with the inauguration of services between Ft. Lauderdale in Florida and J. F. Kennedy airport

IMPACT OF a jet ABSTRACT The objective of this experiment is to determine the force exerted by a jet of water on vanes of various shape.Three different shape of vanes;flat plate‚conical cup‚and hemispherical cup are used for this experiment.The results obtain from the experiment are then used to compare with the theoretical results.Force generated on the surface of vane depends on the rate of change of momentum and it can be calculated by recording the time taken for water to reach a certain
