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

Experiment 3 Method of Flow Measurement Objective To demonstrate typical flow measurement devices for incompressible fluids: (1) venturi meter‚ (2) orifice plate and (3) rotameter. To compare the difference in flow rate incurred by each of these device. Overview In engineering and industrial practice‚ fluid measurement of many of the variables and properties‚ such as density‚ viscosity‚ pressure‚ velocity‚ flow rate and etc is one of the problems most frequently encountered by engineers

Mixed economy of Irish welfare Welfare is the state of healthy balance for people (Segal‚ 2009). A good welfare state consists of a public who are happy‚ healthy‚ capable and engaged in society. According to the National Economic and Social Council (2009) well-being relates to one’s physical‚ social and mental state‚ it requires needs being met and people having a purpose. A sense of security is needed both financially and personally. According to Esping-Andderson (1990) there are three worlds

CHAPTER 19 SPECIAL TOPICS IN REA MODELING SUGGESTED ANSWERS TO DISCUSSION QUESTIONS 19.1 Often it takes several sales calls to obtain the first order from a new customer. Why then does Figure 19-1 depict the relationship between the Call on Customer and Take Customer Order events as being 1:1? When a sales person visits a customer it is represented by the event Call on Customer. Although single sales call may be followed by many orders from a customer over time‚ it is easier and more

Archimedes’ Principle method instead of submerging the object? If the object was dropped into the beaker‚ then the measurements would not be correct. F. How did the magnet’s density measurement using the Archimedes’ Principle compare to the density measurement using the calculated volume? Which method might be more accurate? Why? The calculated volume measurement is more accurate because Archimedes’ Principle might have a higher percentage of error.

then computing with them. This type of data is either nominal or ordinal. Nominal The number we assign to some object‚ idea‚ or behavior is entirely arbitrary‚ although in some cases a tradition may establish the rules of assignment. If measurements are assigned arbitrary numbers‚ they are called nominal numbers‚ and their sole purpose in the analysis is to differentiate an item possessing one characteristic from an item possessing a different characteristic. Nominal data is a type of categorical

Lab #3 January 30‚ 2012 1. Title: Laboratory Techniques and Measurements 2. Purpose: The purpose of this lab is to learn laboratory techniques and to how to measure precisely. During this lab I will learn how to measure length‚ temperatures‚ volume‚ density‚ and mass using laboratory equipment. I will be using laboratory equipment to prepare dilutions and calculate them while using an algebraic formula. 3. Procedure: In order to perform this lab I needed the following materials:

Basic Lab Measurements and Equipment Purpose This lab experiment displays the accuracy of scientific measuring equipment. This experiment also helps to familiarize the students with these instruments. Procedure: Measure Volumes and Masses 1. Obtain a 400mL beaker and record its mass in grams. 2. Add 40mL of water to the beaker and record the volume. 3. Records the beaker’s mass now with the added water 4. Transfer the water from the beaker to a 50mL graduated cylinder and record the measurement
