Does anybody know the equation Hevacomp uses to convert loading units to flow rates based on the BS EN 806-2006 method? Thanks.
Duncan BrownHi Duncan,
Appreciate I am a little "late to the party" since this is a follow up to a question raised almost four years ago.
My question - I am looking for clarifcation on whether the formula you gave in this answer for BS EN 806 is 100% correct to the software?
Reason is that when I plug your formula into a rudimental excel sheet for QA'ing my teams Hevacomp BS EN 806 outputs - they do not match. I am wondering if it is how the brackets are displayed in your answer which are affecting the results?
What I am trying to do if have a basic Excel sheet where I am plug in the "dim" or "pdim" figures and it'll tell me the flow rate, and I use this when QA'ing outputs generated. Thanks for your help, and hope you had a good Christmas break.
Kind regards
Hi George, happy new year to you. This would be quite difficult to replicate in an excel spreadsheet as the calculation methodology for BS EN806 utilises the rather complex graph shown here. I would suggest perhaps using the graph to QA your results if suitable. I hope that helps.
