Determine the difference in pressure between the centerline points A and B in the two pipelines in Fig. bellow, if the manometer liquid CD is at the level shown. The density of the liquid in AC and DB is row$=800$ kg$/$m$3,$ and in CD$,$ row CD $=1100$ kg$/$m$3.$ a$=66$ mm$,$ b$=229$ mm$.$The difference in the pressure between A and B in $($Pa$)$ is :$......$pa

the difference in the pressure between A and B in mm is $....?$
