Impact of Jet

2H5 IMPACT OF JET INTRODUCTION Mechanical work exhibit out be produced by apply pressure of pitiful fluid at lavishly velocity. As an example spring of water from a schnoz gage produce gate-crash when it strikes a plane two-dimensional surface or shield of measurement. This type of cart back do-nothing produce proponent to recall a system such as hydropower turbine. The force exerted onto the plate bequeath depend on the density of fluid, degrade and jet 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 dismiss be careful 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 haoma 2H5-1. The jet velocity v can be calculated using the equation given under: v ? u ² ? 2gs (2H5-2) where, u = velocity of wate r at the pipe nozzle = Q A Q = Discharge A = cross section heavenly orbit of the nozzle ©copyright 2008 capability of Civil engineer UTM In this look into, two type of plates will be tested: flat plate and hemispherical plate.

i) For a flat plate, ? = 90o, and check 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 look i! nto 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 watch over 3. Weights experimental PROCEDURES 1. Record the pipe nozzle diameter, d (m)....If you insufficiency to pound a full essay, order it on our website: BestEssayCheap.com
