quote:Originally posted by daveshortsIf you are sucking very pure water with no dissolved gasses you can suck up more than 10m but the situation is unstable and if a bubble forms it will grow bigger and bigger as the water boils until it gets back to about 10m height. This is how trees can suck water up their xylae even though they are more than 10m high. In most cases however the 10m limit stands.
quote:Originally posted by daveshortsSorry everyone else:Andrew, your own experiments have prooved that you can (he has syphoned water over 10m) deal with it.
quote:The reason being, is in your vertical tube analogy with a syringe at the top, will inevitably fail, because you are relying on the adhesive qualities of water to maintain the column of water inside the tube, by sticking to the syringe plunger. This cannot and will not work. For example, mercury was used in the same experiment and failed, producing a cavity above the mercury.
quote:Rosy, yes, I have conducted the experiments many times using varying amounts of concentrations of salt, sugar, tea, urine, milk, liquidized leaves from a tree, fruit juice etc. No matter what the concentration is, the flow still occurs. admittedly, there appears to be a varying rate of flow initially.
quote:as for comparing the flow rate to a siphon, at 24 metres or less, the siphon simply does not work over the ten metre level.

quote:Finally, no matter what maths, stats, video evidence, television news footage, school experiments, Invention fair exposure, these experiments receive, you or your colleagues for that matter will still remain unconvinced, no matter how much evidence is before you.
