– Bar (pressure) and size/width

189 views

Hello everyone.

I have a question, which I have no idea how to search for, regarding pressure.

​

1 bar is equal to roughly 10 metres of water

If I have 2 different pipes with water, first is Ø10cm and second is Ø10m, will both have 10 metres of water with 1 bar or will they be different?

​

The way I understand it, bar is “overpressure” (or underpressure), which means both pipes will have 10 metres of water with 1 bar, but the bigger pipe requires more energy to get to 1 bar, compared to the smaller pipe.

​

I’m really bad at explaining, sorry for that.

Are the pipes vertical or horizontal? Are they under external pressure or are we only talking about pressure from the weight of the water? You’ll need to provide a bit more background info to explain what you mean.
