Section: "1"‚ Monday 2-5 pm Title: Date: Venturi Meter and Orifice Meter 6 November‚ 2006 Objectives: • To use the Venturi Meter and the Orifice Meter to measure the rate of discharge. • To determine the coefficient of discharge Cd for both the Venturi Meter and the Orifice Meter. Theory: A Venturi meter and an Orifice are both instruments used for measuring the rate of discharge for a fluid flowing in a pipe. These instruments are based on the same principle which states the following:

of Smart Meter‚ we should know that how many types of meter available in market. In modern days‚ the types of electric meter continuously operate to measure the instantaneous voltage and current and calculating the product of these to give out the instantaneous electrical power. The electric power is then integrated against time to give energy used. 1.1 Types of electric meters There are basically two kinds of electric meter categories‚ the electromechanical and solid state meters. 1.1.1 Electromechanical

Definition: GSM‚ which stands for Global System for Mobile communications‚ reigns as the world’s most widely used cell phone technology. Cell phones use a cell phone service carrier’s GSM network by searching for cell phone towers in the nearby area. The origins of GSM can be traced back to 1982 when the Groupe Spécial Mobile (GSM) was created by the European Conference of Postal and Telecommunications Administrations (CEPT) for the purpose of designing a pan-European mobile technology. It

1. INTRODUCTION 1.1 EMBEDDED SYSTEM: An embedded system is a special-purpose system in which the computer is completely encapsulated by or dedicated to the device or system it controls. Unlike a general-purpose computer‚ such as a personal computer‚ an embedded system performs one or a few predefined tasks‚ usually with very specific requirements. Since the system is dedicated to specific tasks‚ design engineers can optimize it‚ reducing the size and cost of the product. Embedded systems are often

GSM – Overview GSM is a globally accepted standard for digital cellular communications. What is GSM? If you are in Europe‚ Asia or Japan and using a mobile phone then most probably you must be using GSM technology in your mobile phone. GSM stands for Global System for Mobile Communication and is an open‚ digital cellular technology used for transmitting mobile voice and data services. The GSM emerged from the idea of cell-based mobile radio systems at Bell Laboratories in the early 1970s. The
