Homework Statement



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

Homework Equations



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

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

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.
