Assignment 6 Pg 305 2. What is a data flow diagram? Why do systems analysts use data flow diagrams? Answers: A picture of the movement of data between external entities and the processes and data stores within a system. Systems analysts use DFDs to help in the analysis phase by accomplishing the following three things: 1. Requirements Determination 2. Requirements Structuring 3. Alternative Generation and Selection 3. Explain the rules for drawing good data flow diagrams. Answers: Process: A. No

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

ABSTRACT The flow measuring apparatus is designed to study which the most preferable flow meter from different typical methods of measuring the discharge of an incompressible fluid. This can be identify by measuring the flow rate and the head loss with later to be compared to the different flow meter which is venture meter‚ orifice meter and rotameter. INTRODUCTION The objectives of this experiment are to demonstrate the characteristics of some various commonly used methods of measuring fluid flow rates

1. Experimental Methods The aims of this experiment to determine the rate of the reaction by using tubular flow reactor data‚ to demonstrate the temperature dependence of the reaction and also the rate constant and to observe the effect of different flow rates to the conversion. It is a homogenous reaction with only liquid phase is present. Also the reaction is endothermic. The saponification reaction is as follows; NaOH + EtOAc NaOAc + EtOH The reactants were taken as 1:1 ratios. 0.1 M NaOH

History The first structured method for documenting process flow‚ the "flow process chart"‚ was introduced by Frank Gilbreth to members of the American Society of Mechanical Engineers (ASME) in 1921 in the presentation “Process Charts—First Steps in Finding the One Best Way”. Gilbreth’s tools quickly found their way into industrial engineering curricula. In the early 1930s‚ an industrial engineer‚ Allan H. Mogensen began training business people in the use of some of the tools of industrial engineering

The Sippican Corporation Case Study (A) Management Summary Sippican Corporation - a supplier of valves‚ pumps‚ and flow controllers to manufacturers of water purification equipment – faced concerns due to the fact that its competitors have been reducing the price of pumps‚ which was a major product line. According to Sippican’s cost accounting system further decrease in the price of pumps would not be acceptable as because of the past price reductions the margin on pumps have already declined from

The circular flow model reflects the flow of money‚ goods and services throughout the economy. This model is composed of households and business firms and it divides the markets into two categories‚ Product Market and Factor Market. In the Product Market‚ the households consume and purchase the goods and services that are sold by the business firms‚ creating exchange of currency (dollars) between the households who are receiving a finished product and the business firms who are making a profit

Network Flows Case Study MTH221 University of Phoenix February 23‚ 2014 Network Flows Case Study The following is a series of case studies on Network Flows. Network flows can be representative of many types of systems. Whether the network is used to transmit data from computer to computer or server to server‚ transfer goods across the county‚ or deliver liquid flows to the desired location‚ networks must be studied to find the most efficient path for the given media

expenditures. 2.0 Circular Flow between Firm and Households The circular flows between firms and household may therefore be represented by the following 4 flows: Flow of factor of production from household to firms Flow of incomes from firm to household Flow of output of goods and services from firm to households Flow of expenditures from household to firm These four flows are illustrated as appendix 1. Outer flow of incomes and expenditures are flow of money‚ whereas the inner flows of factors of production
