Pressure & Flow v2

[BoxBasher]

The flow, and therefore velocity, will be greater out of the tap spout when it's supplied by larger bore pipe.

If we have a set flowrate of water

9 l/min is 9 l/min, be it blasting down an 8mm pipe at very high pressure or running through an open gutter...

The velocity along the pipe will be higher, but you won't be looking inside the pipe

chuck it down a 22mm pipe (open end)

I meant of course allowing the water to flow from an open ended pipe.

I have a very good spreadsheet for flowrates/friction losses.

I will post a link when I can find it (have posted link here previously)

Cheers. Its only for reference so I can use it when quoting...

Anything on this spreadsheet yet BB?

Can't find the link but I've got it as an excel spreadsheet.
