Pressure measurement with Manometer

  1. Sep 18, 2012 #1
    See Attached...

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

    A manometer is used to measure drop across an orifice plate measuring the flow of brine (salt water, s.g. = 1.260).

    A) If the pressure drop is expected to be approx 1000 Pa, suggest an appropriate fluid. Why?

    B) If the flow rate is anticipated to increase, leading to a pressure drop of approximately 50,000 Pa, suggest an appropriate fluid. Why?

    C) If mercury is chosen as the working fluid, and the height differential (h) is 6.5 inches, determine the pressure differential across the orifice plate.

    D) Which direction is the brine flowing?

    2. Relevant equations

    P1 - P2 = (pf - p)gh

    3. The attempt at a solution

    I'm not sure where to even begin... :(
