By simply taking the IPC flow rates in litres per second and dividing the figure by AS3500 flow rate in litres per second tocompare the two, we get a clear picture of how many times greater the flow rate the IPC is compared to our local standards. All plumbing fixtures have a fixture unit rating, which shows their hydraulic load when compared with a hand basin. Manually adjusting the pipe size to 20mm, you can now see that the velocity of the pipe exiting the hot water unit is now 2.7m/sor changing to 25mm, the velocity is 1.5m/s.
