Homework Help: Fluid Dynamics - Water Storage Tank

  1. Jun 5, 2017 #1
    Hi All,

    Looking for some help (any is greatly appreciated). I've been tasked with the below, and am unable to find a worked example to cross check my work against.

    If anyone with a greater knowledge than me could have a look at the below and advise if I'm right the right track.


    1. The problem statement, all variables and given/known data

    A fresh water storage tank in a factory is shown in the figure above. Its top side is denoted as C, the narrow side as B and the long side as A. In order to allow regular maintenance and cleaning side A is hinged at its bottom edge and secured using a heavy-duty clasp at its top edge. L = 1.25m, H = 0.6m & W = 0.5m

    Side a has a length of 1.25m and height 0.6m

    When the tank is totally full of water:

    a) Calculate the size and location of the water thrust force on side A

    b) Draw a side on view of side A (looking along arrow D) and show the size of the two forces acting on the tank side and how high they are located from the bottom of the tank

    c) Calculate the required resisting force at the clasp to keep the panel shut.

    2. Relevant equations

    See attached workings


    3. The attempt at a solution

    See attached workings

    It is unclear whether you are measuring ##\bar h## from the top or from the bottom.

    I do not understand your calculation of the clasp force. How does a square root come into it?
