Answer:
ρ = 1118.13 kg/m^3
Explanation:
Given:
- The expression for Bulk Modulus B is given as:
B = ρo * ΔP /Δρ
- Seawater has a bulk modulus of 2.3 × 109 N/m²
Find:
Find the density of seawater at a depth where the pressure is 380 atm if the density at the surface is 1100 kg/m³.
Solution:
- The density at any specified depth can be given as:
ρ = ρo + Δρ
- Using the given relation and substitute Δρ:
ρ = ρo + ρo * ΔP /B
ρ = ρo*( 1 + ΔP /B )
- Plug in the values:
ρ = 1100*( 1 + ( 380 - 1 )*10^5 / 2.3*10^9 )
ρ = 1118.13 kg/m^3
