Water and Flux

  1. Aug 19, 2009 #1
    Hi All,

    A friend and I were recently considering the idea of measuring water flow in a fire hose, buy measuring the flux generated by the water moving through the hose. Neither of us are scientific by any means, but I've been trying to research the idea and have not gotten very far.

    I understand that water is a diamagnetic substance and that it can be effected by an external magnetic field, but what I don't fully understand is if \ how any flux is generated when the water flows through something like a hose.

    If there is such a field generated, how practical is it to measure it?

    I'm not sure about how, or even if, what you have in mind is possible. Is there any particular reason for not just inserting a flow meter into the circuit?

    Flow meters are pretty expensive and require you to break the circuit if it's not pre-connected. This is more about, can it be done than a, is it the best solution question.

    Ah... gotcha. Out of my league. There are specialists in fluid dynamics, instrumentation, and electronics who will be able to help you out. Sorry that I can't.
