Referring back to the Blue Book, we can see that 32mm gives a velocity of 1.482m/s which falls within our AS3500 range. Finally we push our headloss calculations into their respective parametersAS3500_Headloss andAS3500_HeadlossSection. An important part of domestic water design is calculating flow and pressure losses, a common complaint I have from fellow Aussies though is that Revits pressure loss report is its not in a familiar format and is not something that theyre comfortable including within their design folders. Laboratory sink . So do you still want to spend the rest of your life measuring pipework? background: none !important; 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.
