The mercury manometer of fig. indicates a differential reading of 0.3 m when the pressure in Pipe A is mm Hg vacuum. Determine the pressure in pipe B. 0.50 m Water Oil 0.15 m 0.30 m Mercury.

Water is flowing in a pipeline, the pressure in the inlet pipe is 20 kPa there is a gradual decrease in pipe diameter and the pressure reading in the reduced pipe diameter is 10 kPa, the reading was via manometer connected to the 2 points. Determine the differential pressure head if the gauge liquid is mercury (S=13.62) in m. *
