Problem of a tank with a trapezoidal section

  1. Aug 22, 2015 #1
    1. The problem statement, all variables and given/known data
    In the figure are the dimensions, and the question is the time in which the take will empty
    Area of orifice 1 cm2
    Discharge coefficient: 0.447
    Gravity 10 m/s2

    2. Relevant equations

    Area of surface = 8x = 8 (2 H) = 16H

    3. The attempt at a solution.

    The red lines are the tank. And I prolongate the lines of the section to find the relation between "H" and X.

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    A description what you are calculating where (and how your variables are defined) would help. Also, the formulas are much easier to read if you write them here instead of showing the scanned paper.
