Question

The average depth of Indian Ocean is 3 km. Calculate \(\frac{\triangle V}{V}\) given that the Bulk modulus of elasticity for water is 2.2 × 10⁹ Nm^-2, (g = 10 m/s²).

Answer 1

Given, average depth of Indian ocean, h = 3 km
Bulk modulus of elasticity of water, K = 2.2 × 10⁹ Nm^-2 and g = 10ms^-2
∴ Pressure, P = hpg = 3 × 10³ × 10³ × 10
