Question

Water, oil and silver are poured into the vessel

Answer 1

The height of the oil column above the water in the vessel is determined as 2 cm.

Pressure of the vessel

The pressure of the vessel due to water, oil and silver poured into the vessel is determined from mercury column.

let level of mercury = 20 cm + 0.5 cm = 20.5 cm

20.5 cmHg = 205 mmHg

1 mmHg = 133.32 Pa

205 mmHg = 27,330.6 Pa

Height of the liquids in the vessel

P = ρgh

where;

ρ is the density of water, oil and silver respectively

ρ = 1000 kg/m³ + 881 kg/m³ + 10,800 kg/m³ = 12,681 kg/m³

h = P/(ρg)

h = (27,330.6) / (12,681 x 9.8)

h = 0.22 m

h = 22 cm

Height of oil column

Oil is less dense than water and will float on water.

Height of oil column = 22 cm - 20 cm = 2 cm
