Summary :
|
|
A DESCRIPTION OF A SET OF EXPERIMENTS IN FLOW MEASUREMENT IS PRESENTED IN THE PRESENT WORK. THE AIM OF THIS PAPER IS TO ALLOW THE BEST CHOICE OF THE FLOW METER BASED ON FACTORS AS GEOMETRY OF THE INSTRUMENTATION, ACCURACY, RANGE OF APPLICABILITY, COST, COMPLEXITY AMONG OTHERS. THE WORK INTENDS TO HELP THE TEACHING OF THE THEORY IN FLUID MECHANICS. THE EXPERIMENTS ARE CARRIED ON BY MEANS OF DIFFERENTIAL PRESSURE DEVICES WIDELY FOUND IN INDUSTRY. THEY WERE SPECIALLY DEVELOPED TO COVER FUNDAMENTAL CONCEPTS IN MEASUREMENT IN FLUID FLOW. THE BEST UNDERSTANDING OF THE PHENOMENA IS REACHED BY MEANS OF EXPERIMENTS ORGANISED USING ORIFICE PLATES, NOZZLES AND VENTURI TUBES INSERTED IN CIRCULAR CROSS SECTION CONDUITS. PHENOMENA AS "VENA-CONTRACTA" AND SEPARATION OF FLUID CAN BE REPRODUCED AND VISUALISED AS WELL. AT THE END OF THE COURSE, THE STUDENT WILL BE ABLE TO DESIGN ORIFICE PLATES, CONVERGENT NOZZLES AND VENTURI TUBES. |
