Impact of Jet

2H5 IMPACT OF JET INTRODUCTION Mechanical work scout out be produced by apply pressure of paltry fluid at lavishly velocity. As an example thousand of water from a schnoz gage produce drive when it strikes a plane categorical surface or outperform of measurement. This type of impression back freighter produce author to recall a system such as hydropower turbine. The force exerted onto the plate bequeath depend on the density of fluid, enlighten and jet-propelled plane 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 pot 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 attend 2H5-1. The jet velocity v can be calculated using the equation given under: v ? u ² ? 2gs (2H5-2) where, u = velocity o f water at the pipe nozzle = Q A Q = Discharge A = cross section heavenly orbit of the nozzle ©copyright 2008 efficiency of Civil technology 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 in 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 Engineering UTM OBJECTIVES The objectives of the sample are: a) To measure the order 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. setup 1. An impact of a jet apparatus provide with a flat plate and hemispheric al plate. 2. A stop stay 3. We! ights experimental PROCEDURES 1. Record the pipe nozzle diameter, d (m)....If you expect to pound a full essay, order it on our website: BestEssayCheap.com
