Homework Help: Fluids, flow velocity and flow rate.

  1. Sep 9, 2012 #1
    1. The problem statement, all variables and given/known data
    Water is flowing from a container through a 50mm diameter hole at 36 liters a minute. Calculate the flow rate in L/s and the flow velocity through the hole.

    2. Relevant equations

    3. The attempt at a solution
    flow rate all i did was 36L/60s to get 0.6 L/s
    flow velocity is where i am stuck.
    Is it flow rate / Pi x r^2
    So 0.6 / 0.00196 = 305.6 ms-1

    missed a few classes due to illness typical most my assignment that is due was covered in them days i miss. Any help would be great.

    Hi, Sum'Random. Welcome to PF.

    You have the right idea.

    Watch those units. This is not the correct answer.

    ohh i see what i missed, Thank you

    0.6 / Pi x(0.025)^2
    = 305.6
    =0.306 ms
