    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...?

    Why not consult CIBSE??
    Considering the arrogance of your postings why would I bother to 'divulge'?
    I detect another armchair googler.
    Some of us do this for a living as opposed to a hobby.

    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?

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

    Roger, this is a forum.
    The pros come here for a laugh sometimes and at other times to render assistance
    Why should a pro be forced to post something he or she does not want to

    Whats the answer to this...
    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...?

    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?

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