Two pipelines, one carrying oil (mass density 900 kg/m3) and the other water, are connected to a manometer as shown in the figure. By what amount the pressure in the water pipe should be increased so that the mercury levels in both the limbs of the manometer become equal? (Mass density of mercury = 13,550 kg/m3 and g = 9.81 m/s2)
