Head of water

Postby ECRyder » Sat Jan 14, 2012 3:07 pm

I know the head of water is determined by the height of the water level above the ground ie 10 metres high gives 1 bar pressure at ground level - but is that head altered by the amount of water in the storage tank? For instance will a 50 gallon tank of water gives 2 bar of pressure if sited at 10 metres above ground.

NB This is a novices question !

Water head pressure is static pressure caused by the weight of water solely due to its height above the measuring point. The pressure at the bottom of a 40-foot lake or a 40-foot high thin tube would be identical, since only height is involved.

I just got this from the internet. It explained the point better than I could
