Hello everyone I'm new here:D I'm doing a project on siphons and I'm trying to understand how a practical siphon works. I did a hell of a lot of reading and the explanations havd gotten jumbled up due to so many misconceptions. So anyways I conducted some experiments and a few strange things happened.
One, I switched round the long and short sides of the tube and the siphon still worked(suspect that has to do with tensile strength or something, my tube was only as wide as a straw), then I was measuring how changing the height of liquid effects the rate of water flow and I got a curved graph any explanations?
And as for the driving force, the one that's convinced me the most is atmospheric pressure, indirectly due to the formation of a partial vacuum in the bend of the tube.
Lastly I tried blocking out the atmospheric pressure expecting the siphon not to work, it did (tell me that's not suposed to happen and that I must have done something wrong)
-thanks in advance
