Requirements

The student who will gain the most from this course will come equipped with some knowledge of fluid systems and an acquaintance with process valves. For these reasons, we strongly recommend that prior to taking the present course, you attend first our courses :

1. Valves : Principles, Operation & Design

2. Flow of fluids through piping systems, fittings, valves and pumps

3. Designing piping systems : Pipe, fittings, flanges and valves

Please note that the mathematics in this course is undemanding. All the work can be done with a hand-held calculator with powers, roots and log functions.

To further help you in this task, the course is accompanied with a Valve Sizing Spreadsheet. The Valve sizing spreadsheet will help you perform all the calculations that we will discuss further ahead in the course. It has all the sizing equations, numerical constants and other parameters built right into it.

We assume that Microsoft Excel is installed on your computer and that you have basic knowledge of using Excel.

Description

––––––––––––––––––––-MAJOR COURSE UPDATE:We have added a quiz at the end of each section to help you test your knowledge and emphasize the key learning points. The quiz includes:True/False questionsMulti-choice questionsImages, cross-sectionnal viewsSolved problemsand much more…When you think you’ve got a good grasp on a topic within the course, you can test your knowledge by taking the quiz. If you pass, wonderful ! If not, you can review the videos and notes again or ask us for help in the Q&A section.––––––––––––––––––––-Designed around a series of practical examples which we work through to a solution, this valuable online course is an essential guide to understanding the valve sizing procedure. This understanding is a prerequisite for a successful operation of your plant and piping system.In this course, we will present a step-by-step sizing methodology. We will show you how to proceed in the sizing of a valve in the daily practice, how to determine the flow coefficient (Cv) when selecting a control valve size, how to predict the maximum flow rate that a selected valve will pass or how to determine the pressure differential that a selected valve will exhibit, just to name a few…You will learn from our industrial experience what we wrongly calculated during project startup, debottlenecking and commissioning. This should undoubtedly help you minimize the mistakes in the sizing and selection of your valves.Included in this course is access to a valuable Valve Sizing Excel Spreadsheet. This tool will help you perform all the calculations that we will discuss further ahead in the course. It has all the sizing equations, numerical constants and other parameters built right in.The Valve Sizing Excel Spreadsheet provides well organized technical data in form of spreadsheet calculations indispensible for anyone involved in the sizing of valves. It presents formulae and data for :Valve flow coefficients CvFlow of fluids through valvesPressure drop through valves and attached fittingsValve Reynolds Number calculationsPredicting maximum flow through valves in choked conditionsRepresentative values of valve capacity factorsAnd much more…The spreadsheet includes two worksheets :Sizing for liquids (incompressible fluids)Non vaporizing flow conditionsChoked flow conditionsSizing for vapors and gases (compressible fluids)So as you can see here, detailed technical descriptions and basic step-by-step instructions will be provided to you along with practice sessions, quizzes, a valuable Valve Sizing Spreadsheet and numerous downloadable resources, to emphasize the key learning points.So with no further ado, check out the free preview videos and the curriculum of the course and we look forward to seeing you in the first section.WR TrainingSpread the wings of your knowledge–––––––––––––––IMPORTANT NOTES : VALVE SIZING SPREADSHEETWe assume that Microsoft Excel is installed on your computer and that you have basic knowledge of using ExcelThis Valve Sizing Excel Spreadsheet includes Visual Basic for Application function subroutines (VBA).
