Is there a maximum 15 mm pipe length from the 22 mm ring?

[Steelmasons]

Which doesn't apply to a pipe.
Kw from the end of the pipe remains the same when the flow rate remains the same.

Are you saying that the end number changed to 30 will deliver 17 kilowatts to the room with the exact same flow rate?

You completely miss the point.
How would you calculate the heat carrying capacity for 22mm tube @ a velocity of 0.5 m/s along with a temp differential of 10c...?

 

[Dan Robinson]

explain that it was an empirical formula.

What else was it going to be?

No idea. Care to divulge the secret?

Why not consult CIBSE??
Considering the arrogance of your postings why would I bother to 'divulge'?
I detect another armchair googler.

Thought I might consult you

It might help you sleep better.

Nah not me.

You do calculations for a living?

Is this a roundabout way of you admitting that you and @D_Hailsham haven't a scooby?

 

[Roger928]

I never has a Scooby. Don't know about DH.
But in the interests of helping the OP steelmatron should post the formula.

 

[Steelmasons]

Bollacks.

Are you just here to rile agile?

Whats the answer to this...

I'll take a pop at guessing..
20kw?

But you were the one (or one of) the ones spouting their CIBSE book saying things were impossible - surely you know the answers?

The questions was "How...."

 

[Roger928]

No need to know how. But the OP might.
Am I right? 20kw?

 

[Dan Robinson]

No need to know how

How's that then?
