Homework Help: Manometer problem solving.

  1. Sep 30, 2013 #1
    1. The problem statement, all variables and given/known data

    Two pipes are connected by a manometer shown in the figure.

    2. Relevant equations

    FR = [itex]\gamma[/itex]*hc*A

    yR = yc + [itex]\frac{I_xc}{y_c*A}[/itex]

    3. The attempt at a solution

    PB - PA = [itex]\gamma[/itex]water*1.1m - [itex]\gamma[/itex]Fluid*0.6m + [itex]\gamma[/itex]water*0.8m = 3.33 kPa

    I checked my answer and it was all okay except the answer was supposed to be -3.33 kPa. Can someone brief me on why that is?

    The problem asked for PA-PB, and you calculated PB-PA.
