    Understanding Fluid Flow in Physics Lab: Poiseuille Equation

    I think at the beginning of the experience the velocity of water through the pipe is greater and we don't have a laminar flow...so the best measure will occur at long times when (y-y0) is small .. what do you think about that ??

    Understanding Fluid Flow in Physics Lab: Poiseuille Equation

    That's what I'm looking for ! Maybe the first part from t = 0s to t= 30s because we have a straight line like Chestermiller said ...

    Understanding Fluid Flow in Physics Lab: Poiseuille Equation

    @haruspex if I have an error Δy on y I can eventually calculate the error on τ by the method of partial differentiation.. @Chestermiller I know because we obtain this curve experimentally and there is certainly another factors that interfer. That's why the teacher as what's the best part of...

    Understanding Fluid Flow in Physics Lab: Poiseuille Equation

    Hi everyone, I have to answer some question about a physics lab..here are the questions A tank is empty by a pipe and we measure the height (y-y0) of fluid in the tank as a function of time. We obtain this graph ( I join the graph) We can find the relaxation time with the relation : with...
