static pressure

Between the header tank and the highest part of the system, or if thats too tricky the next highest part not counting the tank.

It could be the highest radiator, or a circuit pipe running through a roof space.

Surely that would be the definition of the "minimum static pressure" in the system?

And the maximum static pressure would be at the bottom!

Very important aspects in an 11 story block!

Apparently tall flats often have a pumped feed potable water cistern on the roof and a pressure reducing valve every three floors to maintain a usable water supply pressure.

Ah, this is one of those threads!

1 bar = 100,000 Newtons per square metre

force(Newtons) = mass (kg) x acceleration (Gravity, = 9.81m/s/s)

So 1 bar is 9.81 metres head of water, not exactly 10.

So Agile, if the pump is fitted by the hot water cylinder (tank in the loft), what would the static pressure be at the pump? Thank u.

So the term 1 bar means 2 bar because , conventionally, we are all at approx 1 bar = 1 atmosphere to start with and relative pressure is measured against this, the 1 bar is 1 bar above this figure?
