How much is the cross sectional area for the tube to fill up the compartment?

  1. Dec 5, 2012 #1
    1. The problem statement, all variables and given/known data
    abstract question, but we can assume the
    volume,V to be filled is 0.0001m3 and
    time for it to filled up water is 60seconds,
    water density is 1000kg/m3,
    so how much should be the cross sectional area,A for the tube?


    2. Relevant equations
    Volume flow rate=delta Volume/delta time
    Volume flow rate= cross sectional area*velocity of water

    Relavant Picture:
    When 0.0001m3 of water is filled up in the compartment, the compartment of the verge will move downward as shown in the rightside of the picture.

    You need an equation for how flow rate depends on length of tube, cross-sectional area of tube, pressure difference along the tube and properties of the fluid. See what you can find online.

    So is this equation is needed to be used?

    Volume flow rate= cross sectional area*velocity of water
