Question

Toricelli’s barometer used mercury. Pascal duplicated it using French wine of density 984 kg m-3. Determine the height of the wine column for normal atmospheric pressure.

Answer 1

Answer:

Density of mercury, ρ

1

=13.6×10

3

kg/m3

Height of the mercury column, h

1

=0.76m

Density of French wine, ρ

2

=984kg/m3

Height of the French wine column =h

2

Acceleration due to gravity, g=9.8m/s

2

The pressure in both the columns is equal, i.e.,

Pressure in the mercury column = Pressure in the French wine column

ρ

1

h

1

g=ρ

2

h

2

g

h

2

=ρ

1

h

1

/ρ

2

=13.6×10

3

×0.76/984=10.5 m

Hence, the height of the French wine column for normal atmospheric pressure is 10.5 m.
