Explanation Given: Specific gravity of the oil ( SG oil ) is 0 .85 . Level of the water in the cylinder container ( h H 2 O ) is 3 m . Level of the oil in the cylinder container ( h oil ) is 3 m . Density of the water ( ρ H 2 O ) is 1000 kg / m 3 . Acceleration due to gravity ( g ) is 9.81 m / s 2 . Calculation: Calculate the density of the oil ( ρ oil ) . ρ oil = SG oil × ρ H 2 O = ( 0.85 ) ( 1000 kg / m 3 ) = 850 kg / m 3 Calculate the pressure difference between the top and bottom of the cylinder ( Δ P total )
