Homework Help: Venturi Meter

  1. Jun 12, 2010 #1
    1. The problem statement, all variables and given/known data
    Describe how a venturi device for measuring the flow of water in a pope works and estimate the slowest flow rate such a device could be expected to measure using 20% of cross sectional area constriction and a mercury manometer.

    2. Relevant equations
    I also know how to find the pressure

    3. The attempt at a solution
    I am not sure how to find the "slowest rate" in this question. This question is one of my past year exam questions and i am studying for my exam in 6 days. so if someone can guide me on how to make a start that would be great.
