Kitchen tap - laminar flow

[gordon.hunter]

Hi all, looking to buy a new kitchen tap and have noticed in the tech specs of the tap it has a laminar flow.

I am looking for it to have minimal splashing like aerated water flow.

Will laminar flow also achieve this? What is laminar flow? Will it splash like a normal tap?

I would opt for an aerated flow mixer tap however the specific one I am buying does not come in an aerated flow version.

It's a Hans Grohe Focus with Pull Out Spray in Steel Optic

What is laminar flow?

Fluid flow is either "laminar flow" or "turbulent flow", and the Wikipedia pages for those two terms have illustrations (and lots of maths).

Whether this is what the marketing department of Hans Grohe mean when they say "laminar flow" is another matter....

Consider it to be high volume, low pressure and no aeration stream of water and I don't think you'll be far wrong!

How can it be high volume and low pressure?

I have decent water mains pressure and combination boiler.

 

[Burnerman]

Imagine a water pipe, allowing water to pass through at a steady full stream.....that's high volume. Increase the pressure and the water will squirt out of the pipe for a much greater distance.
So I reckon your tap will give a full flow of water, but not at such a pressure to make it squirt straight out of the bowl.

Very easily - they aren't the same thing. A larger outlet will have a lower working pressure and greater flow rate than a small outlet

Yes but we are not talking estuaries here. Talking taps.

Doesn't Hans Grohe have a helpline with people who have scripts to read out explaining these things in simple language.

It does not help that our education system results in 90% of the population confusing pressure and flow rate.

When a kitchen tap manufacturer claims its product produces 'laminar flow' it sounds very much like they have been reading the latest edition of "Snake Oil"

And?

Well you clearly know much more about this than I do, so I shall bow to your vastly superior knowledge and butt out

old bath taps for example are high volume low pressure, which is why they are crap when you convert them to a combi
