FLOW MEASUREMENT (Venturi meter‚ Orifice Plate and Rotameter) OBJECTIVES To study the characteristics and applications of various flow measuring device (venturi meter & orifice plate). To calculate the volume flow rate of water from the pressure difference of both venturi and orifice devices. To compare between theoretical and actual volumetric flow rate through the discharge coefficient concept. To know how rotameter works. INTRODUCTION The measurement of fluid flow is important in applications

I will discus the history of earthquakes‚ the kinds and locations of earthquakes‚ earthquake effects‚ intensity scales‚ prediction‚ and my own predictions. An earthquake can be defined as vibrations produced in the earth’s crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibrations can range from barely noticeable to a disastrous‚ and destructive act of nature. Six kinds of shock waves are generated

seismic activity caused by the build-up of tension at the three types of plate boundaries: destructive‚ constructive and conservative. The pressure is suddenly released as the plates jerk past each other‚ sending out seismic waves from the focus that travel through different parts of the earth. The movement of convection currents within the Earth’s mantle causing the crust to become mobile which creates the different types plate margins‚ makes the cause due to physical factors. However human activity

Gondwana: Nothofagus or Southern Beech. A genus of around 40 extant species of trees. 3. Describe the theory of plate tectonics and identify its role in the formation of Australia as an island continent: The theory of plate tectonics states that Earth’s crust and the outermost part of the mantle are mechanically connected to each other. This layer is broken into several plates that move about Earth’s surface. As they move about‚ they are constantly interacting with each other along their boundaries

There are four major factors that often contribute to the formation of hydrothermal copper porphyry: 1) readily available mineralizing fluid solutions that dissolve and transport metals‚ 2) openings in rocks which allow permeable flow of hydrothermal fluids and the metals that they transport in solution‚ 3) available sites within the fractured rocks which allow for deposition of the minerals from solution‚ and 4) the requisite chemical reactions that contribute to that deposition (Bateman‚ 1967)

Over time plate movement or subduction causes increasing strain on "sticking points" within the crust. Similar to if you rub two pieces of sand paper together‚ they will initially resist sliding until enough strain is built up. At that point‚ the "sticking point" is weakened and releases the built up strain. Before this theory was developed‚ scientists were unsure whether earthquakes caused faulting (plate movement) of faulting caused earthquakes. Today‚ over
