Impact of Jet

2H5 IMPACT OF JET INTRODUCTION Mechanical work establish out be produced by apply pressure of despicable fluid at lavishly velocity. As an example kB-propelled plane of water from a beak gage produce part when it strikes a plane straight off surface or master of measurement. This type of advertise back tin abide produce reason to recall a system such as hydropower turbine. The force exerted onto the plate bequeath depend on the density of fluid, dispatch and jet velocity. The force is also depends on whether the plate is at moving or stationary condition. Theoretically, the force of water jet striking on a static plate can be compute development the following equation: F ? ?Qv (1 ? cos ? ) (2H5-1) where v is a velocity of jet as it strikes the plate and ? is the deflection fee as shown in variety 2H5-1. The jet velocity v can be calculated using the equation given under: v ? u ² ? 2gs (2H5-2) where, u = velocity of wat er at the pipe nozzle = Q A Q = Discharge A = cross section celestial orbit of the nozzle ©copyright 2008 strength of Civil engineering science UTM In this look into, two type of plates will be tested: flat plate and hemispherical plate.

i) For a flat plate, ? = 90o, and fit to Equation (2H5-1), the force exerted on the plate can be calculated as, F ? ?Qv ii) (2H5-3) For a hemispherical plate, ? = 180o, and according to Equation (2H5-1), the force exerted on the plate can be calculated as, F ? 2 ?Qv (2H5-4) FIGURE 2H5-1 ©copyright 2008 Faculty of Civil Engineerin g UTM OBJECTIVES The objectives of th! e prove are: a) To measure the magnitude of force exerted on: i. ii. b) horizontal plate. Hemispherical plate. To compare the forces obtained from the experiment and the actual force calculated using theoretical formula. utensil 1. An impact of a jet apparatus provide with a flat plate and hemispherical plate. 2. A stop set 3. Weights experimental PROCEDURES 1. Record the pipe nozzle diameter, d (m)....If you pauperization to pound a full essay, order it on our website: BestEssayCheap.com
