Question

The pressure in the pressurized water tank is measured by a multi-fluid manometer with one end open
to the atmosphere. Determine the absolute pressure of air in the tank (pressure at point 1) assuming
that the air pressure is uniform. The densities of mercury, water and oil are 13,600 kg m /m 3 , 1000 kg m /m 3 ,
850 kg m /m 3 , respectively. h 1 = 25 cm, h 2 = 35 cm and h 3 = 50 cm.
