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

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

Meltdown at Jet Blue Sherri Hernandez XBIS/219 February 22‚ 2013 Donna Rosentrater Meltdown at Jet Blue There were many problems going on at Jet Blue when there was a really bad storm on Valentine’s Day in the year of 2007. Many airports had to completely shut down and cancel all of their current flights because the weather had such bad conditions. This was a result of freezing rain and sleet. Many passengers were very irate and angry because their flights were delayed or either cancelled

. The four phases of a business cycle are trough‚ recovery‚ peak‚ and recession. The length of an average business cycle can be anywhere from 2-15 years. Capital goods and durable goods last‚ and therefor purchases can be postponed. This may happen when a recession is predicted to be lurking. Durable goods industries therefor suffer large output declines during recessions. However‚ consumers cannot postpone the buying of nondurables; therefore recessions only slightly reduce non-durable output

steam jet refrigeration system: - The boiling point of a liquid changes with change in external pressure. In normal conditions‚ pressure exerted on the surface of a liquid is the atmospheric pressure. If this atmospheric pressure is reduced on the surface of a liquid‚ by some means‚ then the liquid will start boiling at lower temperature‚ because of reduced pressure. This basic principal of boiling of liquid at lower temperature by reducing the pressure on its surface is used in steam jet refrigeration

Jet Streams Jet streams are strong westerly winds that blow in a narrow band in Earth ’s upper atmosphere at the same altitudes at which airplanes fly. They form because of temperature variations between the poles and equator. There are two occurrences that results in the Jet Streams. The first occurrence would be when hot air rises from the tropics towards the North and South Poles subsequently the second occurrence is as the hot air is moving to the north and south poles from the tropics‚ the

The core product of this industry is to sell a fraction of the plane but owners can choose sizes of share‚ cabin volume‚ and types of aircraft that best match their needs. Most shares are sold
