Hi guys,
got a little problem I'm currently working on and looking for some input/sanity check.
Firstly i have a round tank within a round tank both with open tops, the inner tank is suspended within the outer tank such that there is a gap between both tanks bottoms faces, the inner tank open top is lower than the outer tank top opening such that a head difference is present to encourage siphoning through a transfer pipe in the middle of the inner tank.
the outer tank is 3/4 full of a fluidized sand and 1/4 water on top which overflows, the inside tank has a transfer pipe in the center of its bottom face to allow the transfer of fluidized sand, the length of this pipe is half way above the mid line of the outer tank and the top of the inner tank is 500mm lower than the top of the outside tank, thus 500mm head difference.
so with the sand at 0.75h and the height of the open end of the transfer pipe on the inner tank being roughly 0.5h my question is will the fluidized sand try to equal its level between the inner and outer tank, thus creating a flow until the two fluidized sand teeter beds are level in both tanks?
i cannot seem to find a similar example with formula which i can use to calculate what may happen.
