Asealed tank contains oil (sg 0.83) for a height of 2 m and air at an absolute pressure of 136.3 kpa above the oil. if a piezometer is attached to the side of the tank at the bottom, what will be the height of oil column within the piezometer?

The height of oil column will be 6.298 meters.

Explanation:

The oil in the piezometer will rise until the pressure of the oil column formed balances the pressure at the bottom of tank.

Using the equation for pressure in a fluid at rest we have

Applying values we obtain value of pressure at bottom of tank as

Now the pressure at the bottom of the oil column in the piezometer equals

Equating the 2 pressures and solving for 'h' we get

answer: report them
