Thanks for all of the replies - most helpful!
This, in conjunction with a discussion with my college lecturer, I feel a lot more satisfied with my knowledge of hydraulics in a heating system now.
Cheers!
I assume the answer to my following question will be fairly fundamental, but for some reason I can't seem to get my head around it...
What I'm confused with is the relationship between static head, dynamic pressure and total system pressure, with specific regard to a heating system.
Logic...
Firstly, thanks for all of the replies.
I did forget to mention I am in the UK so this obviously will differ from other practices, such as those in America.
Scotty - as I assumed, the separation of the phases is purely for safety reasons. As you mentioned though, it would be quite difficult to...
It would, indeed. Some rooms require several circuits. What I would like to know is why I need to keep each phase separate within the rooms. Say I'm supplying a computer suite with 3No. ring circuits, they would all need to be from either L1, L2 or L3. Why can't they be mixed? For instance: one...
I'm sure the question I'm about to ask has a very simple answer, yet it's one that I'm not aware of!
When designing circuits from a 3-phase dis bd. why are single phase loads separated between rooms/areas? I understand there is a p.d. between the line conductors of 400V, but why must they be...
