quote:I believe you will find that the negative tension inside the inverted U tube at 20 metres will be far higher than your estimate.
quote:Atmospheric pressure will support a 10m column of water. This will give a vacuum pressure above the water (0Atm) We know that. (I think?)
quote:When the water level goes below the 10 M level in the Barometer type experiment, it is then supported by a vacuum.
quote:In the Inverted U tube experiment, there is twice the weight applied to the column of water suspended over the raised middle of the tube, and therefore twice the amount of tension is applied to the water inside the tube, yet it remains relatively stable providing the gas has been removed from the water by pre-boiling it.
quote:Strousburger already did it by killing the tree and observing water transpiring from the leaves for three weeks
quote:What would you, or anyone else reading this expect to happen to the water in the end exposed to the atmosphere via the U shaped exit point, and the central T junction was elevated to 2 metres vertical?
quote:A simple thought experiment for you to consider Imagine the inverted U tube experiment set up, but this time, the two open ends are submerged in one sealed container, with the water level afording some air space above it. And it has all the pressure removed eliminating any positive pressure or influence from the atmosphere.
quote:Prediction, the water column will remain intact. What do you think? B.T.W thinking about a way of testing this one to settle an argument.
quote:In the case of the barometer type experiment, "Thought experiment again unfortunately" removing the poitive pressure in this experiment by sucking the air out of the beaker containing the water with the open end of the capped water filled tube will indeed cause the water to be pulled from the top of the capped tube at a much lower height than ten metres. But this does not prove that the pressure was the only force supporting it. It suggests that the increased downward force of the water has severed the hydrogen bonds to the capped glass tube.
quote:I was trying to refer to the way a syringe pulls water up, even when there is air space directly in front of the plunger. The absence of pressure if you like is sufficient to draw water up acting upon its surface, so why do you think the vacuum is any different to the suction caused by the plunger in a syringe?
