    Good morning all. I have a question that I am really struggling with and I was wondering if anybody on here would be able to help? Please see the question below:

    Question: use dimensional analysis toestimate the time of an ideal liquid outflow from the cylindrical tank with crosssection of A1 and high of h. In the bottom of the tank is a small hole withcross section of A2. In order to find solution you have to assume that:
    The fluid velocity does notdepend on the diameter of the hole.
    The time of outflow is inverselyproportional to the cross section of the hole.
    The time of outflow is directlyproportional to the cylinder cross section.

    Additionally, on the base of your calculations pleasedescribe the relationship between time outflow and liquid density.


    I am struggling to attach my attempt. I will continue to try but any help would be greatly appreciated!!!

    You could try uploading the image of your work to something like this: http://tinypic.com and then posting the link?

    I'm doing dimensional analysis at the moment, but I want to see your work first before I try and help just in case we are learning different methods!

    Thanks for the reply! The method does not matter and I am keen to learn a new way if it makes it easier. I'm pretty sure my answer is incorrect.

    Please find the link to my first page below. I will try and upload my second page now. ☺

    Thank you for the tip on how to get the images of my workings uploaded. Apologies for the orientation.

    I fear that my solution doesn't answer the question. Can somebody provide me with a solution to the question at the top of the thread?

    Right I've had a look, and I haven't done Inspen's rules, I've only done the pi theorem. So I don't think I can help.
