Test: Fluid Pressure & Measurement - Civil Engineering (CE) MCQ

The left leg of a U-tube mercury manometer is connected to a pipeline conveying water, the level of mercury in the leg being 0.6 m below the centre of pipeline, and the right leg is open to atmosphere. The level of mercury in the right leg is 0.45 m above that in the left leg and the space above mercury in the right leg contains Benzene (specific gravity 0.88) to a height of 0.3 m. Find the pressure in the pipe in metres of water.

The pressure, in meters of oil (sp. gr, 0,8), equivalent to 80 m of water is
