A venturi meter with a diameter of 30 cm at the entrance and 15 cm at the throat, is connected to a vertical pipe of diameter 30cm carrying oil of specific gravity 0.9. The difference in elevation of the throat section and the entrance of the venturi meter is 30 cm. The mercury manometer shows a gauge deflection of x = 1000mm.
Determine
1) the discharge of oil; and
2) the pressure difference between the entrance section and throat section.
The coefficient of discharge is 0.98 and the specific gravity of the mercury is 13.6.
