The output of the python node then feeds into a math divide node and we divide our flow rate figures by 28.317 and pushes the result to a flow based parameter that Ive named AS3500_PSD. This system is used in some buildings where there are a greater number of floor levels than would be acceptable for a single-stack system. Based on the IPC sizing charts, 1 fixture unit is 3 gallons per minute, or 0.18l/s whereas in AS3500, 1 loading unit is 0.09l/s. img.wp-smiley, For example, changes in lifestyle and flexible work hours .

In Dynamo, our formula is quite clean and simple, in fact if you squint a little, it looks just like our original Excel formula. What interested me the most is that many hydraulic designers have told me I dont use Barrie Smith as his results oversize the pipework but you can see in the comparison that Barrie Smith and AS3500 are almost identical, with AS3500 actuallyreturning probable simultaneous flow rates higher than that ofthe Blue Book fromaround the 22 fixture unit mark. Ratings for plumbing fixtures ways in which Standards Australia gives effect to that commitment Standards is! The Standard applies to new installations as well as alterations, additions or repairs to existing installations. Revit will also oversize branches of pipework connected to a larger fitting as shown below with the HWU. So with a powerful tool like Revit at your disposal, why not utilise it to generate data outputs that are in that familiar format and that you are happy to drop into your design notes? Material tags displaying '?' DirectShape pyramids If using a litre per second flow rate, make sure that it is based on a probable simultaneous flow value.Ive used probable simultaneous flow in my example, which based on the Barrie Smith Blue Book is 0.21l/s.

The main goal of the demonstrated workflow was to keep things as simple as possible, which I guessends upmaking it a workaround rather than a true workflow, but it something that everyone is able to get access to without knowledge of coding for the Revit API. Besides the incorrect use of a meme or two, what it all means is that we can make some simple tweaks to our family content to start using the Revit pipe sizing tool for Australian Standard compliant pipework. This system differs from the fully vented system in that each connection to the stack is vented, however, some trap vents are omitted.
