A pipe flowing water has a manometer attached, as shown in the figure. The local atmospheric pressure, Po, is 101.3 kPa and the gravitational acceleration is 9.81 m/s². The densities of the water (pw), oil (Pon), and mercury (pug) are 1000.0, 800.0 and 13,600 kg/m³, respectively. The heights of the liquid levels in the manometer system are indicated in the figure. What is the absolute pressure at the center of the water pipe, Pw, in kPa.

A pipe flowing water has a manometer attached, as shown in the figure. The local atmospheric pressure,
Po, is 101.3 kPa and the gravitational acceleration is 9.81 m/s². The densities of the water (pw), oil (po«),
and mercury (png) are 1000.0, 800.0 and 13,600 kg/m³, respectively. The heights of the liquid levels in the
manometer system are indicated in the figure. What is the absolute pressure at the center of the water
pipe, Pw, in kPa.
