The height of the mercury column in a barometer is found to be 67.0 cm at a certain place.
What would be the height of a water barometer at the same place? (densities of mercury-
1.36 × 104
kg/m3
and water- 1.0 × 103
kg/m3
).

---

Let the pressure due to water be h1 ?1 g1 and that of water be h ? g. Then
h1 ?1 g1 = h ? g. Hence h1 = (6.7 × 10-1
) × (1.36 × 104
) / 1.0 × 103
= 911.2 cm or 9.11 m.
